Rotary Shafts with Retaining Ring Grooves
With Retaining Ring Grooves on Both Ends
Clip retaining rings into the grooves to separate and position gears, sprockets, and bearings. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances. Made of 303 stainless steel, they are more corrosion resistant than steel shafts but also more difficult to machine.
