    Step-Down Rotary Shafts

    A shoulder acts as a stop for gears, sprockets, and bearings as well as components with smaller bore sizes. No need to machine these rotary shafts or install a shaft collar. Turned, ground, and polished to tight tolerances, they reduce vibration, evenly distribute loads, and improve accuracy.
