Bridgeport 12193502 Draw Bar Assembly J-head Milling Machine

Product Description

The BRIDGEPORT 12193502 is a draw bar assembly designed for use with Bridgeport J-Head milling machines. The draw bar is a critical spindle-retention component that secures cutting tool holders and arbors inside the milling machine spindle. Without a properly functioning draw bar, tool holders cannot be clamped securely, creating an unsafe condition and degraded machining accuracy. This assembly is an OEM-sourced replacement part intended for installation by qualified machine tool technicians or millwrights performing preventive maintenance or component replacement on J-Head top housing configurations.

This draw bar assembly is specifically matched to the J-Head top housing found on Bridgeport I Series milling machines. It is suited for job shop environments, vocational training facilities, and production floors running Bridgeport-style knee mills. Typical installation scenarios include replacing a worn, bent, or stripped draw bar as part of spindle service, or restoring a machine to operational condition after extended use. The assembly ships as a complete unit, reducing the need to source individual hardware components separately.

Key Features

• OEM-matched draw bar assembly for correct thread engagement and spindle fit
• Designed specifically for J-Head top housing configurations
• Compatible with Bridgeport I Series milling machines
• Ships as a complete assembly for straightforward replacement
• Direct replacement reduces downtime during spindle service

Compatibility

Designed for use with Bridgeport I Series milling machines equipped with a J-Head top housing. Verify your specific machine model and spindle configuration before installation to confirm fitment.

Installation Notes

Draw bar service is typically performed by a millwright or qualified machine tool technician. Power down and lock out the machine at the main disconnect before accessing the spindle or top housing. Do not overtighten the draw bar, as excessive force can damage the spindle taper or tool holder threads. Refer to the machine manufacturer service documentation for proper draw bar engagement procedure.
