KPSA2-50J28 is a plastic spur gear in the KPSA series, with module 2, 28 teeth, and a 28mm pitch diameter. It has a 20° pressure angle, is made of MC901 nylon, and features a standard full-depth tooth profile. The gear includes a keyway of 8 mm width × 3.3 mm depth conforming to JIS B1301 (Js9 tolerance), with a backlash of 0.14 mm, and weighs 0.17 kg. It is rated for an allowable torque of 14.9 N·m (1.52 kgf·m). The gear is designed for use with steel hubs where high temperature, large diameter, or reverse-load impacts require enhanced securement, and backlash values are theoretical for matched pairs under normal conditions. Permanent dimensional changes may occur under variable temperature or humidity conditions.
