KNSU2.5 plastic spur gears with steel cores feature a module of 2.5, 12 teeth, a 55 mm pitch diameter, a 60 mm outside diameter, a 25 mm face width, a 15 mm hub width, and a 40 mm total length. The gear is made of MC602ST nylon fused to an S45C steel core using a diamond knurling process for high holding strength. It meets JIS grade N9 precision (JIS B1702-1:1998) with a 20° pressure angle and standard full-depth teeth. The allowable torque is 1.33 kgf·m (13.0 N·m) with a backlash range of 0 to 0.46 mm. The hub bore is not explicitly stated for this variant, but the series has a 35 mm hub diameter for the 22-tooth configuration. Dimensional stability and performance are maintained across a wide temperature range, up to 140°C.
