Plastic spur gears with a steel core, designed for use with a 3 mm module and 34 teeth, feature a 60 mm hub diameter and 102 mm pitch diameter. The gear has a face width of 30 mm, a hub width of 17 mm, and a total length of 47 mm. It is constructed of MC602ST nylon fused to an S45C steel core, with JIS grade N9 precision and a 20° pressure angle. Allowable torque is 39.0 N·m (3.98 kgf·m), and backlash is specified as 0-0.56 mm. The gear's holding strength is achieved through a diamond-knurled metal surface prior to nylon casting, ensuring dimensional stability and high-temperature performance up to 140°C.
