KNSU1.5 series plastic spur gears with steel cores, 1.5 module, feature a 40 mm pitch diameter, 15 mm face width, and a 12 mm hub width, with a nominal 40 mm bore. The gear has a bending strength of 6.00 N·m (0.61 kgf·m) and a theoretical backlash of 0~0.40 mm, weighing 0.31 kg. The gear teeth are standard full depth with a 20° pressure angle and comply with JIS grade N9 (JIS B1702-1:1998). The core is S45C steel, fused to MC602ST nylon using a knurled and grooved interface for high holding strength under temperature variations up to 130-140°C. All variants share the same material, precision, and construction method.
