KPU1-80 is a plastic spur gear with a stainless steel core, module 1, 80 teeth, and a bore diameter of 40 mm. The gear is made of MC901 nylon and features a precision JIS grade N9 tooth profile with a 20° pressure angle. It has an outside diameter of 82 mm, face width of 10 mm, and total length of 45 mm. The allowable torque is 3.34 N·m, and the theoretical backlash is 0~0.36 mm. The metal core is fused to the nylon using a diamond-knurled surface and grooves, ensuring high holding strength and dimensional stability over a wide temperature range. The design minimizes thermal expansion effects and provides clean aesthetic appearance without fasteners.
