PIN - HAIR - COTTER (Raymond RA811-557)

RA811-557: A damaged cotter pin can lead to unintended disconnection of critical linkages. During inspection, a hairpin-style cotter may show deformation or cracking from repeated vibration. Keeping a cotter pin in sound condition helps secure pivot points in mechanical assemblies. This aftermarket replacement part references Raymond catalog number RA811-557. The pin functions as a locking fastener, inserted through a hole to prevent axial movement of a mating component. A common failure consequence is that a worn or missing cotter pin allows a clevis pin or shaft to walk out, causing sudden loss of control. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.01 pounds.
