Plastic spur gears with a steel core, designed for use in precision applications, are available in a module 2.5 series with a 44-tooth configuration. The gear features a 15 mm face width, a pitch diameter of 110 mm, an outside diameter of 115 mm, and a hub diameter of 65 mm, with a total length of 75 mm. The gear is manufactured from MC602ST nylon with an S45C steel core, featuring a 20° pressure angle and standard full-depth teeth. Precision conforms to JIS grade N9 (JIS B1702-1:1998). The allowable torque is 31.3 N·m (3.19 kgf·m) and backlash is specified as 0~0.48 mm. The product design ensures secure fusion between the nylon and core via diamond-knurled surface treatment, promoting dimensional stability and high holding strength, even under temperature variation from -20°C to 120°C.
