Bridgeport 12180064 Clutch Sleeve Milling Machine Part

Product Description

The BRIDGEPORT 12180064 is a clutch sleeve replacement part designed for Bridgeport-style milling machines. The clutch sleeve is a mechanical drivetrain component that engages and disengages the spindle drive, allowing the operator to control spindle rotation without shutting down the motor. This part is installed by qualified machine tool technicians or maintenance machinists performing scheduled maintenance or component-level repairs on vertical knee mills. It is an OEM-style replacement intended to restore proper clutch engagement function and maintain accurate spindle control.

This clutch sleeve is suited for vertical knee milling machines where the original clutch sleeve has worn, cracked, or failed to engage reliably. It is used in machine shop environments ranging from small job shops to production facilities. Installation typically occurs during a drivetrain inspection or as part of a broader spindle head rebuild. Technicians sourcing this part are generally working from a service manual or performing a direct component swap against a worn original.
