Plastic spur gear with steel core, module 2.5, 68 teeth, made of MC602ST nylon with an S45C metal core, featuring a 70 mm hub diameter, 170 mm pitch diameter, 210 mm outside diameter, 30 mm face width, 47 mm total length, and an allowable torque of 90.6 N·m. Precision meets JIS grade N9 (JIS B1702-1:1998). The gear employs a diamond-knurled metal core with grooves for strong nylon fusion, ensuring dimensional stability across temperature variations. Backlash is 0~0.48 mm. The series omits the J40 suffix, which appears to be a trailing order code not affecting the base specification.
