It has a bore diameter of 65 mm, an outside diameter of 145 mm, a face width of 25 mm, and a total length of 105 mm. The gear is rated for an allowable torque of 42.1 N·m (4.29 kgf·m) and complies with JIS grade N9 precision (JIS B1702-1: 1998). The metal core is S45C, fused to MC602ST nylon via a diamond knurl and groove process to ensure strong mechanical bonding. Frontal backlash is 0 to 0.48 mm. It is designed for operation in a wide temperature range with good dimensional stability. The product is intended to be mated with steel gears to avoid heat buildup due to plastic-on-plastic friction.
