KEY - WOODRUFF (Mitsubishi MB091300050)

A damaged woodruff key can cause a drive component to slip or fail entirely. This aftermarket replacement part references the Mitsubishi catalog number MB091300050. The key's plain mechanical function is to positively locate and transmit torque between a shaft and a hub. A concrete generic failure consequence is that a worn or sheared key may allow the hub to spin freely on the shaft, leading to sudden power loss. During inspection, a woodruff key should be checked for deformation or cracking. Verify the serial number or application, then call (562) 693-7748. This part is a woodruff key, a type of key used in mechanical assemblies.
