KSSA1-24 is a steel hubless spur gear with a module of 1, 24 teeth, and a tooth width of 10 mm, made from S45C steel with a hardness of less than 194 HB and precision grade JIS N8 per JIS B1702-1:1998. It has a 20° pressure angle and standard full-depth teeth. The allowable torque is 0.76 kgf·m, with a theoretical backlash of 0.050 mm. The gear is designed for use without modification, as secondary operations that reduce tooth width may compromise precision and strength. The catalog does not list a variant with the exact part number KSSA1-24J10, but the series matches KSSA1-24 with a 10 mm bore by default. The KSSA1-24 is available in S5 tooth shape with a bore diameter of 8 mm, making it unsuitable for a 10 mm finished bore unless modified, which is discouraged. The series summary applies.
