Product Overview<\/h2>\n

\"Korea<\/p>\n

Plastic bevel gears<\/strong> transmit motion and light torque between intersecting shafts with a set of properties that no metal gear can offer simultaneously: self-lubrication, corrosion immunity, electrical insulation, low noise, and the ability to be injection-moulded to net shape at low per-unit cost in high volumes. Korea Ever-Power produces plastic bevel gears<\/strong> in straight and spiral tooth forms from module M0.15 through M2.0, covering outer diameters from \u03a63 mm to \u03a6120 mm. Standard gear ratios \u2014 1:1, 2:1, 3:1, 4:1, and 5:1 \u2014 are available in part-numbered series; custom ratios and modules are accepted to customer drawings.<\/p>\n

The plastic materials available span five engineering polymer families: POM (acetal), PA (nylon, including PA66 and PA12), PPA (polyphthalamide), PBT (polybutylene terephthalate), and PEEK (polyether ether ketone). Each has a distinct combination of strength, temperature resistance, moisture absorption, and chemical resistance that determines which applications it suits. The operating temperature range of the standard series is \u221240\u00b0C to 80\u00b0C \u2014 covering the full ambient temperature range of most consumer, automotive, and light industrial applications. PEEK variants extend the upper limit significantly for higher-temperature environments.<\/p>\n

For applications where the bore must be retained on a shaft positively \u2014 rather than relying on the plastic material’s grip \u2014 Korea Ever-Power offers a brass insert and setscrew option (suffix “BS” in the part number). The brass insert is moulded or pressed into the hub, providing a metal-threaded bore that resists the setscrew load without risk of the thread stripping or the boss cracking under the clamp force. All plastic bevel gear<\/a> sets are vacuum-packed with a plastic tray for transit protection; DHL, TNT, FedEx, and UPS delivery are available.<\/p>\n

Five Engineering Plastics \u2014 Which One to Specify<\/h2>\n
\n
\"plastic<\/div>\n
\n

The performance of a plastic bevel gear depends on the polymer as much as the tooth geometry. Three properties drive material selection for most applications: dimensional stability (how much the gear changes size with temperature and moisture), load capacity (how much torque the tooth can carry before yielding), and chemical resistance (what lubricants, cleaning agents, and process fluids the gear can contact). The five materials below cover the practical range of plastic bevel gear applications.<\/p>\n

\n

POM (Acetal \/ Delrin) \u2014 Best Overall for Precision<\/strong><\/p>\n

Low moisture absorption (0.2% at equilibrium), high dimensional stability, self-lubricating surface layer, and excellent fatigue resistance make POM the default material for precision plastic bevel gears where dimensional consistency over time matters. POM gears retain their tooth profile dimensions reliably across the \u221240\u00b0C to 80\u00b0C operating range. Resistant to fuels, oils, and most solvents; not suitable for strong acids, bases, or concentrated oxidisers.<\/p>\n<\/div>\n

\n

PA (Nylon, PA66 \/ PA12) \u2014 Best for Impact and Quiet Running<\/strong><\/p>\n

PA absorbs more moisture than POM (PA66: 2.5\u20133.5% at equilibrium in humid conditions) and its dimensions change accordingly \u2014 a 10 mm bore can grow by 0.05\u20130.10 mm after prolonged high-humidity exposure. However, moisture absorption also reduces brittleness and improves impact resistance. PA is quieter in mesh than POM at the same tooth geometry, and its lower tooth stiffness damps tooth engagement noise effectively. Specify PA12 rather than PA66 where moisture absorption must be minimised; PA12 absorbs approximately 0.7% moisture and offers better dimensional stability in humid environments.<\/p>\n<\/div>\n

\n

PPA, PBT, PEEK \u2014 High-Performance for Demanding Conditions<\/strong><\/p>\n

PPA (polyphthalamide) and PBT (polybutylene terephthalate) extend the upper service temperature beyond standard nylon, resist automotive fluids more aggressively, and offer better stiffness at elevated temperature than PA66. PEEK is the premium option \u2014 with a continuous service temperature above 200\u00b0C, excellent chemical resistance including concentrated acids and bases, and dimensional stability that exceeds all other engineering plastics in the range. PEEK plastic bevel gears are used in sterilisable medical devices, aerospace actuators, and chemical process equipment where no other plastic meets the combined temperature, chemical, and load requirements.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Brass Insert and Setscrew Option \u2014 When to Specify “BS”<\/h2>\n
\n
\"plastic<\/div>\n
\n

The standard plastic bevel gear has a bore machined directly in the plastic hub. This works reliably for light drives where the gear is a loose to transition fit on the shaft, relying on friction and an adhesive or retaining compound for axial and rotational retention. It is the lower-cost option and is appropriate for most consumer electronics, toy, and light instrument applications.<\/p>\n

The brass insert option \u2014 indicated by the suffix “BS” in the part number \u2014 replaces the plain plastic bore with a brass insert that is either moulded into the hub during injection moulding or pressed in post-moulding. The brass insert carries a threaded setscrew hole. This configuration provides:<\/p>\n

    \n
  1. Metal threads that resist stripping<\/strong> \u2014 the setscrew engages a brass thread rather than a plastic one. Under repeated tightening and release cycles (maintenance, adjustment), plastic threads strip and the gear becomes loose on the shaft. Brass threads maintain their grip over the product’s service life.<\/li>\n
  2. Resistance to clamp force cracking<\/strong> \u2014 tightening a setscrew against a plastic hub concentrates hoop stress in the boss material. POM and PA can crack under this stress, particularly at low temperatures where the material is more brittle. The brass insert carries the hoop stress in metal, protecting the surrounding plastic.<\/li>\n
  3. Positive axial retention<\/strong> \u2014 the setscrew bears directly against the shaft, preventing axial movement even under the axial thrust loads that a bevel gear generates during operation. Without positive retention, a bevel gear on a smooth bore can walk axially along the shaft, shifting the contact zone toward the heel.<\/li>\n
  4. Compatibility with flatted or grooved shafts<\/strong> \u2014 the setscrew can be tightened against a flat or keyway on the shaft, providing rotational retention that a plain bore cannot achieve without adhesive.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n
    \n

    When to choose BS:<\/strong> Specify the brass insert option whenever the gear drives a continuous load (not just inertia), the shaft experiences axial load from the bevel tooth geometry, the drive reverses direction, or the setscrew will be tightened and released more than two or three times during the product life. For single-use or light inertial drives where the gear is never removed after assembly, the plain bore version is sufficient.<\/p>\n<\/div>\n

    Plastic vs. Metal Bevel Gears \u2014 Choosing the Right Approach<\/h2>\n

    \"plastic<\/p>\n

    Plastic and metal bevel gears are not interchangeable alternatives \u2014 each suits a distinct range of applications. A common design approach mixes the two: a metal pinion drives a plastic wheel, or vice versa. Understanding when each material serves best avoids over-specifying expensive metal gears in lightly loaded applications and under-specifying plastic gears in drives where the load exceeds the polymer’s capacity.<\/p>\n

    \n
    \n
    \u2705 Choose Plastic When<\/div>\n
      \n
    1. Load is light \u2014 below approximately 2\u20135 Nm depending on module and material<\/li>\n
    2. Lubrication is not available or not maintainable (sealed for life assemblies)<\/li>\n
    3. Corrosion resistance is required in the gear bore area or tooth flanks<\/li>\n
    4. Noise reduction matters and load allows a plastic gear to serve<\/li>\n
    5. Weight minimisation is a design constraint<\/li>\n
    6. High-volume production where injection moulding reduces per-unit cost<\/li>\n
    7. A “sacrificial” driven gear is acceptable \u2014 the plastic gear wears first, protecting the metal driver<\/li>\n<\/ol>\n<\/div>\n
      \n
      \u274c Choose Metal When<\/div>\n
        \n
      1. Continuous torque exceeds the plastic material’s tooth bending strength at operating temperature<\/li>\n
      2. Operating temperature exceeds 80\u00b0C continuously (unless PEEK is specified)<\/li>\n
      3. Dimensional tolerance of the bore and tooth profile must be held to metal-level accuracy over years of temperature cycling<\/li>\n
      4. Shock loads or sudden reversal are present and plastic tooth impact resistance is insufficient<\/li>\n
      5. Service life must extend beyond the wear limit achievable in plastic at the operating load<\/li>\n
      6. The drive is classified as safety-critical and plastic gear failure is an unacceptable failure mode<\/li>\n<\/ol>\n<\/div>\n
        \n
        \u2699 Metal Driver + Plastic Driven<\/div>\n

        A common pairing in office automation, consumer electronics, and light industrial drives: the steel or aluminium pinion (driver) meshes with a POM or PA wheel (driven). The metal driver maintains tooth accuracy and stiffness; the plastic wheel damps noise through its inherent vibration absorption and runs without lubrication against the metal surface. The plastic wheel wears at a slow, predictable rate and is a lower-cost replacement item than the machined metal pinion. Visual inspection of the plastic wheel’s tooth wear indicates when the set is approaching replacement \u2014 the metal pinion typically outlasts three or four plastic wheels.<\/p>\n<\/div>\n<\/div>\n

        Applications<\/h2>\n

        Korea Ever-Power plastic bevel gears ship to customers across the following sectors. Material selection, tooth form, and the optional brass insert choice vary by sector \u2014 the guide below outlines the typical combination for each.<\/p>\n

        \n
        \n

        \ud83d\udcbb Office Automation & Consumer Electronics<\/h3>\n

        Printer paper-feed drives, copier scan-head drives, barcode scanner angle drives, and camera pan-tilt mechanisms. POM at Module 0.5\u20131.0 with standard bore (no BS) is typical \u2014 the drives run intermittently at light load, are never opened for maintenance after assembly, and benefit from POM’s dimensional stability in the controlled office environment.<\/p>\n<\/div>\n

        \n

        \ud83d\ude97 Automotive Interior Mechanisms<\/h3>\n

        Window regulators, seat position adjusters, sunroof drives, and HVAC damper actuators. POM or PPA with brass insert (BS) \u2014 the drive must retain positive shaft engagement through temperature cycles from \u221240\u00b0C to +80\u00b0C in the vehicle interior, and the setscrew must not loosen due to thermal expansion cycling. PPA suits applications near the engine compartment where peak temperatures exceed the POM limit.<\/p>\n<\/div>\n

        \n

        \ud83c\udff0 Food Production Machines<\/h3>\n

        Conveyor angle drives, filling machine actuators, and labelling machine angle heads where food-contact compliance is required. POM with no surface treatment \u2014 POM is FDA-listed for incidental food contact, does not require lubrication that could contaminate the product, and resists the cleaning chemicals used in food processing washdowns. Stainless steel or aluminium pinion driving a POM wheel is the standard configuration.<\/p>\n<\/div>\n

        \n

        \ud83d\udc8a Medical Equipment<\/h3>\n

        Infusion pump angle drives, diagnostic instrument actuators, hospital bed adjustment mechanisms, and portable medical device drives. PEEK for sterilisable applications \u2014 it survives steam autoclave cycles at 134\u00b0C without dimensional change. POM for sealed non-sterilisable drives where cost is a constraint. Both materials are biocompatibility-validated under ISO 10993 for medical device applications.<\/p>\n<\/div>\n

        \n

        \ud83d\udd25 Chemical & Hazardous Environments<\/h3>\n

        Dosing pump angle drives, laboratory instrument actuators, and chemical processing equipment where contact with acids, bases, or solvents is possible. PEEK or PBT depending on the specific chemical and temperature. Both are corrosion-immune; PEEK additionally resists concentrated acids and ketones that attack PBT. Plastic gears are also non-sparking, making them suitable for drives in potentially explosive atmospheres.<\/p>\n<\/div>\n

        \n

        \ud83c\udf81 Toys & Consumer Products<\/h3>\n

        Battery-operated toys, hobby RC vehicles, domestic appliances, and personal care device drives. POM or PA at Module 0.5\u20130.8, injection-moulded at volume for lowest per-unit cost. Toy applications typically use pure plastic-on-plastic meshing without a metal driver \u2014 the loads are low enough that both gears can be plastic, and the absence of metal eliminates any risk of sharp-edge injury from a broken tooth.<\/p>\n<\/div>\n<\/div>\n

        Frequently Asked Questions<\/h2>\n
        \n
        \n

        What is the maximum torque a plastic bevel gear can transmit?<\/p>\n

        This depends on the module, tooth count, material, and operating temperature. As a rough guide for POM at Module 1, a 16-tooth 1:1 pair transmitting torque at 500 rpm can handle approximately 0.5\u20131.0 Nm continuously at 25\u00b0C before the tooth root bending stress approaches the material’s fatigue limit. At 60\u00b0C, the allowable torque drops by approximately 30% because POM’s tensile strength falls with temperature. PA66 at equivalent size is slightly lower in stiffness and fatigue strength than POM. PEEK is significantly higher \u2014 up to three to four times the allowable torque of POM at the same module and operating temperature. For applications near the material limit, submit your torque, speed, and temperature data and our engineering team will run a tooth bending stress calculation before confirming suitability.<\/p>\n<\/div>\n

        \n
        \n

        Why does PA nylon change size after installation and how do I account for it?<\/p>\n

        PA absorbs moisture from ambient air, and this absorption causes the gear to swell. A PA66 bevel gear with a 10 mm bore will grow by approximately 0.05\u20130.10 mm in bore diameter after reaching moisture equilibrium in a typical indoor environment \u2014 this is the bore becoming looser on the shaft. Simultaneously, the tooth pitch diameter grows, changing the gear’s operating centre distance slightly. To account for this, two approaches are used: either design the initial fit with a slightly tighter bore and confirm the gear mesh still runs correctly at full moisture absorption, or specify POM instead of PA where dimensional stability is critical. PA12 absorbs significantly less moisture than PA66 and is the better choice in applications where this dimensional change is a concern.<\/p>\n<\/div>\n

        \n
        \n

        Can plastic bevel gears be used without any lubrication?<\/p>\n

        POM, PA, and PEEK all have self-lubricating properties from their polymer microstructure \u2014 they transfer a thin molecular film to the mating surface during running-in, which reduces the friction coefficient at the tooth mesh. At light loads and moderate speeds, these materials can run without any applied lubricant indefinitely in a clean environment. At higher loads or speeds, where frictional heat build-up in the plastic tooth would raise the gear surface temperature toward the material’s softening point, a light application of grease or oil at the mesh point extends tooth life significantly. The operating condition requiring lubrication varies by material and load; POM without lubrication can typically handle up to approximately 0.3\u20130.5 m\/s pitch-line speed at light load before frictional heating becomes a concern. Above this level, a plastic-compatible grease is recommended.<\/p>\n<\/div>\n

        \n
        \n

        Can you produce a custom module or ratio not listed in the standard part series?<\/p>\n

        Yes. The standard part series covers the most common module and ratio combinations. Custom modules from M0.15 upward, non-standard ratios, and custom bore configurations are accepted to customer drawings or sample parts. Our technical department produces production drawings from customer input and provides them for approval before tooling begins. Provide the module, tooth count on each gear, shaft intersection angle, bore diameter, hub dimensions, and material requirement. Custom tooling lead time varies by module size \u2014 for very small modules below M0.5, specialised tooling may add two to four weeks to the initial order lead time but does not affect repeat orders.<\/p>\n<\/div>\n

        \n
        \n

        How do I specify the right plastic bevel gear for a food-contact application?<\/p>\n

        For food-contact applications, specify POM (natural white grade) or PEEK. Both materials are listed in FDA 21 CFR regulations as suitable for incidental food contact. POM covers most food machine drives at temperatures below 80\u00b0C and is the more economical option. PEEK covers applications where steam cleaning at temperatures above 100\u00b0C is used, or where chemical sanitisers aggressive to POM are employed. For the drive configuration, use a stainless steel metal pinion meshing with the plastic wheel \u2014 this keeps all tooth-contacting surfaces either stainless steel or FDA-listed plastic, with no lubricant required between them. Include “food contact” in your enquiry so we can confirm the specific POM or PEEK grade and supply the relevant compliance documentation.<\/p>\n<\/div>\n

        Can I visit the factory or get drawings and technical data before ordering?<\/p>\n

        Factory visits are welcome \u2014 please notify us at least two weeks in advance so we can arrange the visit schedule. Our technical department produces and provides production drawings and technical data on request for all standard and custom plastic bevel gear products. Drawings are issued in PDF, DXF, or STEP format depending on your requirement. For new custom programmes, a dimensioned drawing showing the proposed tooth geometry and hub configuration is issued for customer approval before any tooling is commissioned. Contact our team<\/a> with your application data and we will confirm feasibility and provide the relevant technical documentation.<\/p>\n<\/div>\n<\/div>\n

        “We use POM plastic bevel gears at Module 0.5 in a sealed paper-feed angle drive for a high-speed document scanner. The previous metal gear set required lubrication that eventually migrated onto the paper path. Switching to POM plastic bevel gears eliminated the lubrication entirely. No contamination incidents in 18 months across 1,200 units deployed in customer sites.”<\/p>\n

        “We assemble window regulator drives for three automotive OEM programmes. The plastic bevel gears<\/a> with brass insert (GB1M016BS) have run through our cold-temperature test at \u221235\u00b0C without setscrew loosening \u2014 a problem we had with the previous plain-bore version whose plastic boss cracked at the setscrew hole. The brass insert solved the problem cleanly without any housing change.”<\/p>\n

        “We manufacture small batch clinical infusion pumps and needed a PEEK bevel gear pair in Module 0.8 that survives 500 autoclave cycles at 134\u00b0C. Ever-Power confirmed PEEK feasibility within three days of our enquiry and provided a production drawing for approval. The gears met our dimensional specification after autoclave cycling in our validation test \u2014 no measurable change in bore or pitch diameter after 500 cycles.”<\/p>\n

        “We run stainless steel pinions against POM wheels in a food packing line angle drive. The POM wheels are the sacrificial member \u2014 they wear visibly while the stainless pinions remain in spec. Replacement is a two-minute job and the POM wheel cost is negligible. The drive has been running this way for three years with four POM wheel replacements and no stainless pinion changes. It is exactly the wear pattern we designed for.”<\/p>\n

        “We used POM bevel gears in a battery-operated RC vehicle drive train. Cost per unit was the main target \u2014 the whole vehicle retails below KRW 30,000. Ever-Power’s Module 0.5 POM bevel pair hit the price point we needed at our production volume, dimensional consistency was good across five production batches, and we have had no warranty returns attributable to gear failure in the first season of sales.”<\/p>\n
