[High Quality Hardened Metal & Smooth Operation] 32P pinion gear set is constructed from hardened metal for extended durability. Precision machining ensures smoother operation with reduced roughness and noise, allowing the gears to roll smoothly. [Pitch & Teeth] 32P is compatible with 0.8 metric (0.8M) pitch. 32P (32DP) refers to the pitch of each tooth on the pinion gear, and 20T, 21T, 22T, 23T, 24T indicate the number of teeth on each gear. Ensure your spur gear and pinion gear have the same pitch for proper meshing. [Compatibility] Designed for use with 1/8 inch bore and 3.175mm shaft size motors. Confirm that your RC motor shaft matches this diameter. [Multiple Gear Options] Offers five different tooth counts to allow flexibility in gear ratio selection for customized speed performance.
