KSSG4-25 is a ground spur gear with a module of 4, 25 teeth, and a 20° pressure angle. It is machined from S45C steel with induction-hardened tooth surfaces, achieving a hardness of 50-60 HRC. The gear has a bore diameter of 20 mm, a pitch diameter of 80 mm, an outside diameter of 100 mm, a face width of 40 mm, and a total length of 65 mm. It meets JIS grade N7 precision (JIS B1702-1:1998) and has a backlash range of 0.14-0.24 mm. The allowable bending strength is 389 N·m and surface durability torque is 213 N·m. The weight is 3.29 kg. Secondary operations on the tooth area are prohibited due to induction hardening.
