It has a 70 mm bore and is rated for an allowable torque of 93.4 N·m (9.53 kgf·m). The gear meets JIS grade N9 precision (JIS B1702-1: 1998) and uses MC602ST nylon fused to an S45C steel core via a diamond-knurled surface process for high holding strength. Backlash is specified as 0~0.56 mm. The gear operates reliably across a wide temperature range and exhibits low dimensional change due to temperature variation.
