KNSU2-28 is a plastic spur gear with a steel core, featuring a module of 2, 28 teeth, a pitch diameter of 56 mm, an outside diameter of 60 mm, a face width of 20 mm, and a hub diameter of 35 mm. It has a JIS grade N9 precision, a 20° pressure angle, and is made of MC602ST nylon fused to an S45C steel core using a diamond-knurled surface process for high holding strength. The allowable torque is 9.05 N·m (0.92 kgf·m), with a backlash range of 0 to 0.44 mm and a weight of 0.27 kg. The gear is designed for stable dimensional performance across temperature variations and is intended for use with steel mating gears to prevent heat buildup. The bore diameter of 35 mm matches the hub diameter, which may exhibit minor serration without affecting strength.
