ORING (JLG JL4291399)

A damaged retaining ring can allow a shaft or bore assembly to separate under load, leading to component misalignment or sudden disengagement. During inspection, a retaining ring's groove fit and spring tension should be checked for secure retention. The retaining ring type provides a removable shoulder that holds bearings, gears, or other parts in position on a shaft or inside a housing. A worn or missing retaining ring may cause a rotating part to shift axially, resulting in noise, vibration, or mechanical binding. Keeping a retaining ring in sound condition helps maintain the intended axial location of assembled components. This aftermarket replacement part references JLG catalog number JL4291399.
