O-RING (Yale YT218K344)

A damaged retaining ring can allow a shaft or bore component to shift out of position, leading to mechanical failure. This aftermarket replacement part references the Yale catalog number YT218K344. The O-ring type retaining ring functions as a circular fastener that seats into a groove to secure assembled parts. A common failure consequence is that a worn or broken ring may cause the retained component to dislodge during operation. Keeping a retaining ring in sound condition helps maintain the intended assembly alignment under load. The part is a simple mechanical element that provides axial retention without requiring additional hardware. Verify the serial number or application, then call (562) 693-7748.
