KSSG4-15 is a ground spur gear with a module of 4, 15 teeth, and a standard full-depth profile at a 20° pressure angle, made from S45C steel with induction-hardened tooth surfaces achieving 50-60 HRC. The gear has a bore diameter of 20 mm, pitch diameter of 45 mm, outside diameter of 60 mm, face width of 68 mm, hub width of 40 mm, and total length of 65 mm. It is rated for an allowable bending strength of 197 N·m and surface durability of 74.1 N·m, with a theoretical backlash of 0.14-0.24 mm and a mass of 1.04 kg. The gear meets JIS grade N7 precision per JIS B1702-1:1998. Secondary operations on the tooth area are prohibited due to induction hardening.
