It has a standard full-depth tooth profile with a 20° pressure angle and meets JIS grade N9 precision (JIS B1702-1:1998). The gear is constructed from MC602ST nylon fused to an S45C steel core using a diamond-knurled surface treatment for high holding strength. The hub diameter is 60 mm, face width is 20 mm, and the total length is 34 mm. It has an allowable torque of 26.8 N·m (2.74 kgf·m) and a backlash range of 0~0.46 mm.
