KNSU2-68 is a plastic spur gear with a steel core, module 2, 68 teeth, and a 60 mm bore, designed for applications requiring dimensional stability and high torque capacity. The gear has a pitch diameter of 136 mm, outside diameter of 140 mm, face width of 20 mm, and total length of 34 mm. It is made of MC602ST nylon fused to an S45C steel core using a diamond-knurled surface process for strong mechanical bonding. The allowable torque is 26.8 N·m (2.74 kgf·m), with backlash ranging from 0 to 0.46 mm. Precision meets JIS grade N9 (JIS B1702-1:1998). Operating temperatures up to 140°C are supported with minimal dimensional change due to full nylon encapsulation of the core. The hub width is 100 mm, and the weight is 1.66 kg.
