Bridgeport 12190166 Feed Drive Worm Gear Milling Machine

Product Description

The BRIDGEPORT 12190166 is a feed drive worm gear designed as a direct replacement component for Bridgeport milling machines. The worm gear is a critical drivetrain part that transfers rotational motion from the feed drive motor to the table feed mechanism, enabling precise table movement during milling operations. Weighing 1 pound, this is a compact but mechanically essential component. It is intended for installation by qualified machine tool technicians or millwrights performing preventive maintenance or drivetrain repairs on Bridgeport I Series milling machines.

This feed drive worm gear is designed for use with Bridgeport I Series milling machines, specifically fitting within the 2J and J-Head Lower Housing assembly. It is commonly replaced during scheduled maintenance intervals or when feed drive irregularities, excessive backlash, or worn gear teeth are identified during machine inspection. This part is appropriate for both job shop environments and production floor applications where Bridgeport knee mills are in active service.

Installation Notes

Installation should be performed by a qualified machine tool technician or millwright.
