KNSU1.5-70 is a plastic spur gear with a steel core, module 1.5, 70 teeth, and a pitch diameter of 105 mm. It has a bore diameter of 50 mm, hub diameter of 105 mm, outside diameter of 108 mm, face width of 15 mm, and total length of 70 mm. The allowable torque is 11.7 N·m (1.19 kgf·m), with a theoretical backlash range of 0~0.42 mm and a weight of 0.70 kg. The gear meets JIS grade N9 (JIS B1702-1:1998) and has a 20° pressure angle with standard full-depth teeth. The material is MC602ST nylon fused to an S45C steel core, with dimensional stability maintained under temperature variation. The core and nylon interface is designed to retain strength despite secondary operations, though thermal and moisture exposure may cause dimensional change.
