The KSS3-18J22 is a steel spur gear in the KSS Module 3 series with 22 teeth, a finished bore of 22 mm, and a keyway according to JIS B1301 (Js 9 tolerance). It is made of S45C steel with a tooth hardness of less than 194 HB, has a 20° pressure angle, and standard full-depth teeth. The gear has a face width of 15 mm and a thickness of 32 mm. Backlash values are specified in the normal direction for a pair of identical gears in mesh. The part includes a set screw (M5 x 7.5 mm) for shaft fastening, though its use is restricted to light-load applications. Allowable torque and durability ratings are calculated under assumed usage conditions. Secondary operations that reduce tooth width are discouraged as they impair precision and strength.
