WOODRUFF KEY (Bobcat BC5J807)

A failed woodruff key can result in sudden loss of torque transmission. This aftermarket replacement part is referenced under the Bobcat catalog number BC5J807. A woodruff key is a half-moon shaped key used to secure rotating components like gears or pulleys to shafts. Its plain mechanical function is to fit into a keyseat on the shaft and a keyway in the hub to transmit torque. A worn or sheared woodruff key can cause the driven component to slip or spin freely, leading to loss of drive function. This type is common in power transmission applications where compact keyway geometry is needed. Verify the serial number or application, then call (562) 693-7748. The item ships at approximately 0.02 pounds.
