RING - BACK UP (Yale YT218-S-915)

YT218-S-915: A damaged retaining ring can allow assembled components to separate during operation. The back-up ring type provides axial retention for shafts or bores under dynamic loads. This aftermarket replacement references Yale catalog number YT218-S-915. Its plain mechanical function is to seat in a groove and prevent lateral movement of adjacent parts. A common failure consequence is that a worn or missing ring leads to component dislodgment and mechanical jamming. Keeping a retaining ring in sound condition helps maintain assembly integrity under vibration. Verify the serial number or application, then call (562) 693-7748.
