Stem Pinions
Stem pinions are specialized gears with a cylindrical shaft extending from the gear body, designed to transmit rotational motion and torque in precision instruments and other applications requiring accurate gear meshing. These pinions are made from materials such as steel, brass, or plastic, and their selection depends on factors like gear ratio, number of teeth, pitch diameter, module, and pressure angle. Properly designed stem pinions ensure smooth, efficient operation and extended component lifespan.
