KSS2-42J15 is a module 2, 42-tooth steel spur gear with a 15 mm finished bore, machined from S45C material with JIS grade N8 precision (JIS B1702-1:1998), a 20° pressure angle, and standard full-depth teeth. It has a keyway conforming to JIS B1301 Js9 tolerance and includes a set screw. The gear weighs 1.01 kg and has a theoretical backlash of 0.18~0.36 mm. The tooth hardness is less than 194 HB. Secondary operations that reduce tooth width are not recommended as they compromise precision and strength. Set screws are supplied with tapped hole variants, denoted by an asterisk.
