KEY - WOODRUFF (CAT CT00333-04016)

A damaged Woodruff key can cause a shaft-mounted component to slip or fail under load. During inspection, a worn or sheared key may prevent proper torque transmission between the shaft and hub. This aftermarket replacement part references the CAT catalog and carries the part number CT00333-04016. The Woodruff key type provides a positive mechanical lock between a rotating shaft and a mating part. A common failure consequence is sudden loss of drive or timing, leading to unexpected downtime. Keeping a Woodruff key in sound condition helps maintain reliable rotational alignment. Verify the serial number or application, then call (562) 693-7748.
