Bridgeport 12180093 Draw Bar Washer I Series Milling

Product Description

The BRIDGEPORT 12180093 is a draw bar washer designed for use with Bridgeport I Series milling machines. This hardware component seats between the draw bar and the spindle head assembly, providing a bearing surface that helps secure tooling during milling operations. It is a direct OEM-style replacement part intended for maintenance and repair of vertical milling machine spindle systems. Machinists and machine tool technicians performing draw bar service or toolholder changeouts will find this a necessary consumable component when restoring proper clamping function to the spindle.

This draw bar washer is specifically sized and rated for the 2J-Head Top Housing found on Bridgeport I Series vertical knee mills. It is suited for job shop environments, vocational facilities, and production floors where Bridgeport I Series machines are in active service. Replacement is typically required when the existing washer shows wear, deformation, or corrosion that compromises consistent draw bar torque and toolholder retention.
