Bridgeport 12200111 Spring Pin Milling Machine Part

Product Description

The BRIDGEPORT 12200111 is a spring pin replacement part designed for use in milling machine assemblies. Spring pins, also known as roll pins or slotted spring pins, are cylindrical fasteners that compress during installation and exert outward pressure to hold components in alignment or in place. This pin is an OEM-style hardware component intended for servicing BRIDGEPORT milling machines. It is typically installed by machinist-level service technicians or mill mechanics performing maintenance or rebuilds on the lower housing assembly of compatible head configurations.

This spring pin is specified for use with I Series Milling Machines, fitting the 2J and J-Head Lower Housing assemblies. It is a direct-fit service part suited to shop environments where BRIDGEPORT mills are in regular production use. The part ships as a single-piece unit, making it appropriate for targeted single-point repairs without purchasing hardware in bulk.
