O-RING (Yale YT218-K-356)

YT218-K-356: A damaged retaining ring can allow assembled components to separate under load, leading to mechanical failure. During inspection, a retaining ring may show signs of distortion or cracking that compromise its holding force. This aftermarket replacement part cross-references Yale part number YT218-K-356. The retaining ring functions as a mechanical fastener that seats in a groove to secure a shaft or bore assembly. A common failure consequence is the ring losing tension, which can cause the retained part to shift or dislodge. Keeping a retaining ring in sound condition helps maintain axial positioning of components during operation. Verify the serial number or application, then call (562) 693-7748.
