O-RING (CAT CT27V89C18)

CT27V89C18: A worn retaining ring can allow assembled components to separate unexpectedly during operation. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT27V89C18. The retaining ring functions as a mechanical fastener that holds parts in a fixed position on a shaft or within a bore. When the ring loses its tension or breaks, the secured component may shift or dislodge, leading to operational interruption. In a typical usage context, a failed retaining ring can cause sudden loss of alignment in rotating or sliding assemblies. The part is a simple circular clip that snaps into a groove to prevent axial movement. Verify the serial number or application, then call (562) 693-7748.
