Module 3, 75-tooth ground spur gear made of S45C steel with induction-hardened tooth surfaces hardened to 50~60HRC, conforming to JIS grade N7 (JIS B1702-1:1998). The gear has a 100 mm pitch diameter, 225 mm outside diameter, 231 mm total length, and 30 mm face width. Backlash is specified as 0.14~0.24 mm. Keyway dimensions are 14 x 3.8 mm, and allowable torque is 10.3 N·m (10.5 kgf·m). A set screw is included for hubs with tapped holes. Secondary operations on the tooth area are prohibited due to induction hardening. Variants with set screws are marked with "*" and may have counterbored tapped holes to reduce tap length.
