Plastic spur gears with a steel core, designed for high torque applications and dimensional stability under temperature variation, available in module 2 and module 2.5 variants. The KNSU2-36 model has a 36-tooth count, 2 mm module, 72 mm pitch diameter, 76 mm outside diameter, 45 mm hub width, and 34 mm total length, with a 40 mm bore and an allowable torque of 12.5 N·m (1.27 kgf·m). The gear features an S45C steel core fused to MC602ST nylon via diamond knurling and grooving, with JIS grade N9 precision and a 20° pressure angle. Backlash is 0~0.44 mm, and weight is 0.42 kg. The design eliminates the need for mechanical fasteners, providing a clean appearance and enhanced holding strength. Temperature compensation and safety factors must be applied for operational torque calculations.
