Designed as an OEM-style replacement clutch ring pin for Bridgeport vertical milling machines requiring part number 12190188.
Installation should be performed by a qualified machine tool technician or experienced machinist. Disconnect and lock out all electrical power to the milling machine before accessing the spindle clutch assembly.
