38-Teeth Yellow Plastic Spur Gear with Set Screw

The 38-Teeth Yellow Plastic Spur Gear serves as an ideal intermediate or output gear in custom mechanical reduction builds. Engineered with a dual-extended center hub and a top-mounted set screw, it ensures coaxial stability and prevents shaft wobble during continuous operation. Four circular weight-reduction cutouts provide an optimal balance of strength and low inertia.
