Product Overview<\/h2>\n
\n
\n \"High\n <\/div>\n
\n

High-precision CNC machine nylon plastic gears for transmission<\/strong> are nylon gear components \u2014 spur, helical, worm gear, rack and pinion \u2014 produced by CNC machining (turning, milling, hobbing, and broaching) from nylon rod, plate, or cast block for use in transmission mechanisms. Product name: Nylon plastic gear. Processing: CNC machining. Features: high resistance. Korea Ever-Power’s CNC-machined nylon transmission gears cover the complete range of transmission applications: from vehicle steering rack and pinion mechanisms (where nylon’s self-lubricating, no-backlash-growth property gives rack-and-pinion steering a better feel than recirculating ball), to industrial conveyor drives, to precision instrument gear trains \u2014 serving applications where injection moulding is insufficient for the required precision, size, or quantity.<\/p>\n

Korea Ever-Power’s CNC nylon transmission gears<\/a> are used initially in low-power precision motion transmission applications and increasingly in high-power transmission applications \u2014 the evolution of nylon material grades (PA66+GF50, MC Nylon, oil-casting) has expanded the torque capacity of plastic transmission gears to levels previously achievable only with metal.

Plastic Rack and Pinion for Transmission \u2014 Design and Performance<\/h2>\n

\"measuring<\/p>\n

Racks and pinions are the most common linear transmission mechanism \u2014 converting rotary motor motion to linear axis motion. CNC-machined nylon rack and pinion sets offer compelling advantages over metal alternatives in transmission applications:<\/p>\n

\n
\n

Rack and Pinion Shape \u2014 Rectangular vs Circular<\/h3>\n

Traditional racks and pinions are rectangular \u2014 the rack is a linear gear with straight teeth on a flat bar. They can also be circular or crescent-shaped. For circular racks, the teeth of the gear are cut into the rod in a crescent shape. Circular nylon racks are generally less strong than rectangular racks and require careful design \u2014 they should be installed with sleeve bearings or other supports as they are unsuitable for continuous rotation under high radial loads. Korea Ever-Power manufactures both rectangular and circular nylon racks by CNC machining, and confirms the correct design for each application before production.<\/p>\n<\/p><\/div>\n

\n

Vehicle Steering \u2014 Rack and Pinion Advantages<\/h3>\n

Racks and pinions are most commonly used in the steering mechanism of wheeled vehicles. The rack and pinion mechanism offers less mechanical advantage than a recirculating ball but has lower backlash and a better steering feel \u2014 the linear relationship between steering wheel rotation and wheel angle gives the driver more precise steering feedback. It can be driven hydraulically (HPAS) or electrically (EPS). For EPS steering systems, plastic nylon rack and pinion components \u2014 particularly the nylon-coated or nylon-insert rack \u2014 are standard, providing the self-lubrication, noise reduction, and anti-stick-slip properties required for smooth electric power-assisted steering feel.<\/p>\n<\/p><\/div>\n

\n

No Lubrication Required \u2014 Key Transmission Advantage<\/h3>\n

A significant advantage of plastic nylon rack and pinion is that it does not require lubrication. This property makes plastic racks and pinions an excellent alternative to metal gears in transmission mechanisms where lubricant maintenance is impractical or where lubricant contamination is unacceptable. Initially used in low-power precision motion transmission applications (instrument drives, camera systems), nylon rack and pinion is now used in high-power transmission applications \u2014 particularly EPS rack assemblies \u2014 as nylon material grades have advanced in strength and fatigue performance. Korea Ever-Power supplies both small precision and large industrial CNC-machined nylon transmission rack and pinion components.<\/p>\n<\/p><\/div>\n

\n

Lifting, Clamping, and Industrial Uses<\/h3>\n

Racks and pinions vary widely in application but are generally used for lifting and clamping purposes in industrial environments. CNC-machined nylon racks in lifting mechanisms (lab jack drives, adjustable workbench height drives) provide quiet, corrosion-free linear actuation without the lubrication maintenance that steel rack-and-pinion lifting mechanisms require. The ABS and nylon variants in yellow are common in industrial lifting equipment where the coloured plastic rack is a visual safety indicator of the plastic component’s load limit in a mixed metal\/plastic machine.<\/p>\n<\/p><\/div>\n

\n

High-Power Transmission \u2014 Nylon Material Evolution<\/h3>\n

Nylon transmission gears are now used in high-power transmission applications thanks to advances in material grades. PA66+GF50 (50% glass fibre reinforced PA66) achieves tensile strength > 200 MPa \u2014 comparable to die-cast aluminium alloys and approaching low-alloy cast iron \u2014 while retaining nylon’s self-lubricating, lightweight, and corrosion-resistant properties. Korea Ever-Power CNC-machines PA66+GF50 transmission gears for high-power vehicle auxiliary drives and industrial machinery gear stages where the historical load-capacity limitation of standard nylon grades no longer applies.<\/p>\n<\/p><\/div>\n

\n

CNC vs Injection Moulding for Transmission Gears<\/h3>\n

For transmission nylon gears, CNC machining is preferred over injection moulding when: precision above DIN7 is required; the gear is too large for injection moulding (OD > 100\u2013150 mm); quantity is below the injection moulding economic threshold (< 500 pcs); or the nylon grade required (MC Nylon, PEEK, PA66+GF50) is difficult to process by injection moulding. Korea Ever-Power's CNC machining facility handles all these requirements \u2014 enabling the supply of CNC-machined nylon transmission gears where injection moulding is impractical, without compromising the quality and performance required for transmission service.<\/p>\n<\/p><\/div>\n<\/div>\n

\n
\n
<\/div>\n

Vehicle Steering Transmission<\/h3>\n

CNC-machined nylon pinion gears and rack inserts in vehicle EPS steering column and rack assist mechanisms. The steering rack and pinion is one of the most critical transmission components in a vehicle \u2014 low backlash, linear response, and no stick-slip are essential for safe steering control. Korea Ever-Power’s PA66+GF30 CNC nylon pinion gears meet automotive steering gear quality requirements, providing the correct steering feel while reducing weight and noise vs metal pinion alternatives.<\/p>\n<\/div>\n

\n
<\/div>\n

Industrial CNC Axis Drives<\/h3>\n

CNC-machined nylon rack and pinion sets for CNC router and plasma cutting machine axis transmission drives. Initially used only in low-power precision motion transmission (small CNC engravers), high-performance PA66+GF30 and MC Nylon rack and pinion sets are now used in high-power CNC machining centre axis drives (up to 3 kW, 5 m\/min rapid) \u2014 providing quieter, maintenance-free axis drives than equivalent steel rack and pinion sets at 40\u201360% lower component cost.<\/p>\n<\/div>\n

\n
<\/div>\n

Robot Linear Transmission<\/h3>\n

MC Nylon rack and pinion drives in collaborative robot linear slide axes, SCARA robot reach extension drives, and Cartesian robot X-Y stage drives. Robot linear drives require the same no-lubrication, no-contamination, lightweight properties as robot joint gear stages \u2014 CNC-machined MC Nylon rack and nylon pinion sets satisfy all these requirements for the linear transmission stages of modern industrial and collaborative robots.<\/p>\n<\/div>\n

\n

Lifting and Clamping Equipment<\/h3>\n

PA66 and MC Nylon rack and pinion sets in laboratory jack drives, height-adjustable workbench mechanisms, and industrial clamping fixture drives. Racks and pinions are generally used for lifting and clamping purposes in industrial environments \u2014 nylon rack and pinion sets provide the required mechanical advantage for light-to-medium lifting and clamping loads with the maintenance-free operation that industrial users value in fixed equipment installations.<\/p>\n<\/div>\n

\n
<\/div>\n

Precision Positioning Transmission<\/h3>\n

CNC-hobbed nylon gear and rack sets (DIN6 precision) in optical bench positioning stages, spectrophotometer sample drives, and coordinate measuring machine (CMM) probe positioning mechanisms. In these low-power precision motion transmission applications, CNC-machined nylon gears were the original plastic transmission component \u2014 and Korea Ever-Power’s hobbed DIN6 precision nylon gears continue to set the standard for backlash-free, noise-free, maintenance-free precision positioning transmission in laboratory and metrology equipment.<\/p>\n<\/div>\n

\n
<\/div>\n

Agricultural and Outdoor Transmission<\/h3>\n

CNC-machined MC Nylon spur and helical transmission gears in tractor implement PTO drive speed reducers, irrigation system valve actuator drives, and outdoor solar tracker drive gear trains. Agricultural and outdoor transmission gears must withstand UV exposure, temperature cycling, and chemical exposure over service lives of 5\u201315 years without lubrication maintenance \u2014 requirements that MC Nylon and black UV-stabilised PA66+GF30 CNC gears satisfy while metal transmission gears corrode without regular maintenance.<\/p>\n<\/div>\n<\/div>\n

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

When designing a vehicle or machine steering system, what factors should guide the rack and pinion material selection?<\/p>\n

When designing a vehicle steering system, careful consideration should be given to rack and pinion material. Key factors: maximum rack force (total steering effort \u00d7 mechanical advantage ratio \u2014 determines material tensile strength requirement); duty cycle (continuous highway driving vs intermittent parking manoeuvres \u2014 affects fatigue life requirement); temperature range (EPS components experience \u221240\u00b0C to 120\u00b0C \u2014 determines whether PA66, PA66+GF30, or PPS is appropriate); water and salt exposure (chassis-mounted steering rack is exposed to road wash \u2014 corrosion resistance is essential); and packaging envelope (lightweight plastic reduces unsprung mass). Korea Ever-Power engineers evaluate all these factors and recommend the correct nylon grade for each specific steering transmission application.<\/p>\n<\/div>\n
