Bridgeport 12190085 Reverse Trip Ball Lever Milling

Product Description

The BRIDGEPORT 12190085 is a reverse trip ball lever designed as a replacement hardware component for Bridgeport milling machines. This lever is part of the mechanical trip and feed control assembly, providing the operator with directional control over the quill or table feed movement. It is a direct OEM-style replacement part intended for use by machining professionals and maintenance technicians performing routine repairs or refurbishment on shop equipment. The part ships in a single-unit package quantity, making it suitable for targeted single-machine service calls.

This reverse trip ball lever is compatible with I Series Bridgeport milling machines equipped with a 2J or J-Head lower housing configuration. It is commonly installed during overhaul of the feed direction control mechanism, typically when the existing lever shows wear, breakage, or loss of positive engagement in the trip detent. Maintenance machinists and industrial equipment technicians are the primary installers of this component in job shop and manufacturing floor environments.
