KEY - WOODRUFF (Mitsubishi MB1150109)

A damaged Woodruff key can cause a drive component to slip or fail, leading to unexpected downtime. During inspection, a Woodruff key's condition affects the secure alignment of a shaft and its mating part. Keeping a Woodruff key in sound condition helps maintain proper torque transmission between rotating elements. This aftermarket replacement part references Mitsubishi as the OE maker and cross-references part number MB1150109. The key's general function is to prevent relative rotation between a shaft and a hub. A common failure consequence is that a worn or sheared key may result in a loss of power transfer. Verify the serial number or application, then call (562) 693-7748.
