O-RING (CAT CT1916-01102)

A worn retaining ring can allow assembled components to separate during operation, leading to mechanical failure. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT1916-01102. The retaining ring functions as a mechanical fastener that holds parts in a fixed position on a shaft or within a bore. When a retaining ring loses its tension or breaks, the secured component may shift or dislodge, causing unexpected downtime. A common failure scenario involves the ring popping out of its groove under load, resulting in loose hardware. Verify the serial number or application, then call (562) 693-7748 to confirm correct selection.
