KNSU2-56 is a plastic spur gear with a steel core, designed for power transmission with high dimensional stability and temperature resistance. It has a module of 2, 56 teeth, a pitch diameter of 112 mm, an outside diameter of 116 mm, a face width of 20 mm, and a hub diameter of 60 mm. The gear operates with JIS grade N9 precision and a 20° pressure angle. The MC602ST nylon is fused to an S45C steel core using a diamond-knurled surface with grooves, ensuring strong mechanical bonding without bolts or adhesives. Allowable torque is 21.5 N·m (2.20 kgf·m), with a backlash range of 0~0.46 mm. The part is rated for continuous use up to 140°C and exhibits minimal thermal expansion due to full-core encapsulation. Weight is 0.95 kg.
