KSS3-44J40 is a steel spur gear with a module of 3, 40 teeth, and a bore size of 12 mm × 3.3 mm, designed for use in mechanical drives. The gear is made from S45C steel with a tooth hardness of less than 194 HB, has a 20° pressure angle, and conforms to JIS grade N8 (JIS B1702-1: 1998) precision standards. It features a standard full-depth tooth profile. The allowable torque is 2.79 N·m under assumed usage conditions, with a backlash range of 0.20-0.44 mm. The gear is part of a series where keyways are made to JIS B1301 Js9 tolerance and include a set screw for tapped holes. Backlash and torque values are theoretical and based on identical gear pairs in mesh.
