Product Overview<\/h2>\n

Medical bevel gears<\/strong> operate in an environment where the usual engineering trade-offs \u2014 load capacity versus cost, tolerance versus lead time \u2014 are joined by a third axis that has no direct equivalent in industrial or automotive gear supply: patient safety and regulatory compliance. A gear in a surgical robotic wrist carries the surgeon’s motion to the tool tip; any backlash change or dimensional drift over the device’s service life affects the precision of that motion. A gear in a diagnostic imaging gantry must not generate metallic particles that contaminate the radiation beam path. A gear in an infusion pump must not corrode in contact with medical-grade fluids or crack during autoclave sterilisation cycles.<\/p>\n

Korea Ever-Power produces medical bevel gears<\/a> in module M0.15 through M2.2 across a full range of medically acceptable materials \u2014 316L stainless steel with passivation certification, PEEK for autoclavable and biocompatibility-validated applications, aluminium alloys with hard anodising, brass for non-magnetic instrument drives, and polymer materials where load allows a non-metallic approach. Gleason-method cutting is standard, producing the localised contact tooth form that is compatible with the precision housing tolerances common in medical device design. All medical bevel gear orders ship vacuum-packed with a plastic tray; free samples are available before production approval, with air freight charged to the customer.<\/p>\n

The range of accuracy grades available \u2014 ISO 6, JGMA 1, JIS 6, AGMA 13, DIN 6, DIN 5, AGMA 12 \u2014 covers the full spectrum from precision servo-driven robotic drives (AGMA 13 \/ JGMA 1) to general-purpose medical instrument drives (DIN 6 \/ AGMA 12). Price is negotiable based on quantity; for small batch medical device programmes, discuss requirements with our team directly.<\/p>\n

Medical-Specific Material Requirements<\/h2>\n
\n
\"medical<\/div>\n
\n

Material selection for medical bevel gears is governed by four properties that do not appear in industrial gear specifications: biocompatibility, sterilisability, corrosion resistance to body fluids and medical-grade cleaning agents, and the absence of toxic wear debris. The following covers the principal material choices for each medical application context.<\/p>\n

\n

316L Stainless Steel + Passivation<\/strong><\/p>\n

316L is the standard metallic material for patient-contacting and fluid-contacting medical components. The low carbon “L” grade reduces sensitisation risk during welding or prolonged heat exposure. Passivation after machining removes surface iron contamination and maximises the thickness and continuity of the chromium oxide passive layer \u2014 the barrier that gives stainless steel its corrosion resistance. Korea Ever-Power provides a passivation certificate compliant with ASTM A967 or AMS 2700 with every 316L stainless medical bevel gear order.<\/p>\n<\/div>\n

\n

PEEK (Polyether Ether Ketone)<\/strong><\/p>\n

PEEK is the material of choice for medical bevel gears in applications that require autoclave sterilisation (134\u00b0C steam cycles), resistance to hospital disinfectants, and minimal particle generation at the tooth mesh. It is validated for biocompatibility under ISO 10993, is radiolucent (does not interfere with X-ray or fluoroscopy imaging), and its dimensional stability over sterilisation cycling is superior to all other engineering plastics. For sealed-for-life medical instrument drives that will be sterilised with the device, PEEK is the default specification.<\/p>\n<\/div>\n

\n

Brass (Non-Magnetic Instrument Drives)<\/strong><\/p>\n

MRI environments exclude ferromagnetic materials from the scanner room. Medical bevel gears in MRI table positioning drives, patient handling systems adjacent to the magnet bore, and MRI-guided intervention tools use brass or 316L stainless (which is only weakly magnetic in its austenitic form). Brass additionally offers self-lubricating properties that reduce maintenance requirements in sealed medical device gearheads where periodic re-lubrication is not part of the device’s service protocol.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

Gleason Method \u2014 Precision and Localised Contact for Medical Drives<\/h2>\n
\n
\"medical<\/div>\n
\n

Korea Ever-Power uses the Gleason method for all medical bevel gear production \u2014 the same manufacturing approach used for the majority of precision bevel gears worldwide in automotive, aerospace, and medical applications. Two manufacturing methods exist for bevel gears: Gleason and Klingelnberg. They produce different tooth forms and are not interchangeable even at the same module and tooth count. Specifying the correct method is important when ordering a replacement gear for a medical device that is already in service.<\/p>\n

The Gleason method is relevant to medical applications for two specific reasons beyond general precision:<\/p>\n

    \n
  1. Localised contact tolerance<\/strong> \u2014 Gleason-method bevel gears produce a deliberately localised contact zone on the tooth face. In medical device housings that are produced by injection moulding or precision casting rather than metal machining, small deviations from perfect gear alignment are inevitable. The localised contact zone maintains an acceptable load distribution despite these deviations, preventing the edge-contact stress concentration that would accelerate wear in a full-face-contact gear set.<\/li>\n
  2. Compatibility with medical OEM drawings<\/strong> \u2014 most medical device OEM drawings that specify bevel gears reference Gleason geometry, either explicitly or implicitly through the tooth contact zone specification. Producing to Gleason ensures the replacement or OEM gear matches the original contact pattern verification method used by the device designer.<\/li>\n<\/ol>\n<\/div>\n<\/div>\n

    Medical Bevel Gear Applications<\/h2>\n

    \"medical<\/p>\n

    \n
    \n
    \ud83e\udd16<\/div>\n

    Surgical Robotics<\/h3>\n

    Wrist joint bevel gears in minimally invasive surgical robots transmit the surgeon’s console motion to the tool tip at the end of a 45 cm instrument shaft. AGMA 13 accuracy minimises transmission error so the motion at the tool tip faithfully reproduces the surgeon’s wrist movement. 316L stainless with passivation is standard; PEEK for the driven member where sterilisation cycling is required alongside minimal weight.<\/p>\n<\/div>\n

    \n
    \ud83d\udcf7<\/div>\n

    Diagnostic Imaging Gantries<\/h3>\n

    CT scanner and X-ray gantry rotation drives use bevel gears where the axis of rotation must change between the motor and the ring bearing. PEEK or anodised aluminium gears are specified where the imaging beam path crosses the gear location \u2014 radiolucent materials prevent the gear from appearing as an artefact in the reconstructed image. Dimensional stability over the device’s 10\u201315 year service life is a primary requirement.<\/p>\n<\/div>\n

    \n
    \ud83d\udc8a<\/div>\n

    Infusion Pumps & Drug Delivery<\/h3>\n

    Volumetric infusion pumps and syringe drivers use small bevel gear stages to convert motor rotation to the linear plunger drive that displaces fluid. Accuracy is critical \u2014 the gear transmission ratio determines the dose delivered per motor revolution. PEEK or POM gears run without lubrication in the pump mechanism, preventing lubricant contamination of the drug path. 316L stainless for pumps that contact aggressive pharmaceutical solutions.<\/p>\n<\/div>\n

    \n
    \ud83e\udd48<\/div>\n

    Dental Equipment<\/h3>\n

    Dental handpiece angle drives, chair positioning gearheads, and imaging arm actuators use very small module bevel gears \u2014 M0.15 to M0.5 \u2014 in 316L stainless or titanium alloy. Autoclave sterilisation of dental handpieces (134\u00b0C, multiple cycles per day) requires materials and dimensional stability that only metal or PEEK can reliably provide over the handpiece’s service life.<\/p>\n<\/div>\n

    \n
    \ud83d\udd0b<\/div>\n

    Rehabilitation & Prosthetics<\/h3>\n

    Powered prosthetic wrist and finger joints, exoskeleton joint drives, and rehabilitation robot actuators use bevel gears to redirect motor torque at compact joints. Lightweight aluminium or titanium alloy gears reduce the additional mass the patient carries. Biocompatibility requirements depend on whether the gear is within or outside the prosthetic shell \u2014 implanted components require the most stringent material validation.<\/p>\n<\/div>\n

    \n
    \ud83d\udd29<\/div>\n

    Laboratory & Diagnostic Instruments<\/h3>\n

    Centrifuge drives, spectrophotometer optical axis rotation stages, and automated pipetting systems use bevel gears in brass or stainless steel for long-service-life operation with minimal maintenance. Non-magnetic brass is preferred near magnetometer and NMR laboratory instruments. Dimensional stability over years of operation in temperature and humidity-controlled laboratory environments is the primary specification driver.<\/p>\n<\/div>\n<\/div>\n

      Sample policy:<\/strong> Free sample is available for medical bevel gear evaluation. Air freight to the customer is charged in advance or the customer pays the freight cost directly to the courier. For small-batch medical device programmes, the minimum order quantity without shipping is 100 pieces; for volume programmes above 10,000 pieces, a separate pricing tier applies. Contact our team directly to discuss the quantity and pricing structure for your specific programme.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

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

      What passivation standard applies to your 316L stainless medical bevel gears?<\/p>\n

      Korea Ever-Power passivates 316L stainless medical bevel gears per ASTM A967 or AMS 2700, with the passivation method (citric acid or nitric acid) confirmed at the quotation stage based on the customer’s specification or regulatory preference. The passivation certificate states the standard applied, the passivation bath composition, the immersion time and temperature, and the post-passivation test result (water immersion or copper sulfate test per the standard). This certificate is included with the shipment documentation and can be provided in advance for supplier qualification audits.<\/p>\n<\/div>\n

      \n
      \n

      Can PEEK medical bevel gears survive repeated autoclave cycles?<\/p>\n

      Yes. PEEK is one of the very few engineering materials that maintains its mechanical properties and dimensional stability through repeated autoclave sterilisation at 134\u00b0C. In validation testing for medical devices, PEEK specimens are typically subjected to 500 or more autoclave cycles and then measured for dimensional change and tested for residual mechanical properties. The dimensional change is typically below 0.05% after 500 cycles \u2014 negligible for most gear applications. The gear’s bore and tooth profile dimensions remain within the original tolerance after these cycles, which is the critical requirement for a gear that must maintain its mesh geometry throughout the device’s validated service life. Please submit the number of sterilisation cycles and the sterilisation method (autoclave, EtO, or gamma) with your enquiry so we can confirm suitability and any caveats for your specific application.<\/p>\n<\/div>\n

      \n
      \n

      How is price determined for medical bevel gears and is a discount available?<\/p>\n

      Price depends on module, material, accuracy grade, production quantity, and required documentation. The base price for a specific configuration is provided at the quotation stage. Discounts are available for higher quantities \u2014 different price tiers apply at different quantity levels, and the structure is shared as part of the formal quotation. For medical programmes where the annual volume is low (typical of specialist surgical devices) but the quality and documentation requirements are high, the unit price is set to reflect this scope; our team will provide a breakdown showing what each element of the specification contributes to the price so the customer can evaluate trade-offs if needed.<\/p>\n<\/div>\n

      \n
      \n

      What is the minimum order quantity for medical bevel gears?<\/p>\n

      For small-batch medical device programmes, the minimum order quantity is 100 pieces without a shipping requirement. For large-volume programmes (10,000 pieces or above), a separate pricing structure with quantity discounts applies. For some configurations where stock is held, quantities smaller than 100 pieces may be available from existing inventory \u2014 contact our team with the specification and required quantity and we will confirm availability. For initial sample evaluation before committing to a production order, a free sample is provided as described in the sample policy above.<\/p>\n<\/div>\n

      \n
      \n

      What documentation is provided with medical bevel gear orders and how are quality issues handled?<\/p>\n

      Standard documentation includes material certificate, dimensional inspection report, and \u2014 for stainless steel gears \u2014 passivation certificate. For PEEK gears, the material data sheet confirming ISO 10993 status can be provided. Additional documentation \u2014 heat treatment records, first-article inspection reports, SPC data \u2014 is available on request at the quotation stage. Quality issues are resolved immediately: email us the problem with photographs or video showing the failure; we identify the root cause and act on it. Gears damaged in transit under normal packing conditions are covered up to 3% of the delivered quantity. Any quality defect attributable to manufacturing is replaced without charge.
