KPU1.5-30 is a plastic spur gear with a module of 1.5, 10 teeth, and a stainless steel core, designed for applications requiring dimensional stability and wide temperature operation. The gear has a pitch diameter of 45 mm, outside diameter of 48 mm, face width of 15 mm, and total length of 30 mm. It features a 30 mm bore and uses MC901 nylon fused to a SUS303 metal core via a knurled surface process, providing high holding strength. The gear meets JIS grade N9 precision standards (JIS B1702-1:1998) with a 20° pressure angle and standard full-depth teeth. Backlash is 0-0.40 mm, and the allowable torque is 6.60 N·m (0.67 kgf·m). Weight is 0.33 kg. Caution notes state dimensional changes may occur under temperature or humidity variation, and operation without lubrication may require pairing with steel gears to prevent heat buildup.
