KNSU2-34 is a plastic spur gear with a steel core, featuring a module of 2, 34 teeth, 12 mm face width, 68 mm pitch diameter, 72 mm outside diameter, and a 40 mm hub diameter. The gear is made of MC602ST nylon with an S45C steel core, has a standard full-depth tooth profile, a 20° pressure angle, and meets JIS grade N9 precision (JIS B1702-1:1998). It has a bore diameter of 40 mm and a total length of 34 mm. The allowable torque is 11.6 N·m (1.18 kgf·m), with a theoretical backlash of 0~0.44 mm. The gear is designed for use with steel mating gears to avoid heat buildup from plastic-on-plastic contact, and the metal core is mechanically bonded to the nylon via diamond knurling and grooving for enhanced holding strength.
