Bridgeport 11010513 Roll Pin 0.125 X 0.437 in Milling Machine

Product Description

The BRIDGEPORT 11010513 is a roll pin designed for use in Bridgeport I Series milling machines. Roll pins — also called slotted spring pins — provide precise alignment and retention of components within machine assemblies. This pin measures 0.125 inches in diameter by 0.437 inches in length. It is a small but critical hardware component used to secure and locate parts within the machine head, column, or table assembly. Maintenance technicians and machine tool service professionals install this pin during routine repair or component replacement procedures.

This roll pin is intended for use in Bridgeport I Series milling machines in light industrial, vocational, and job shop environments. It is a direct OEM-sourced hardware component, making it a reliable choice when restoring a machine to factory specification. Typical applications include securing gibs, locks, handles, and other mechanical subassemblies where a driven retention pin is required. Single-piece packaging makes it practical for targeted repair work without excess inventory.

Installation Notes

Installation of this roll pin is typically performed by a machine tool technician or millwright. Power down and lockout/tagout the milling machine in accordance with OSHA LOTO procedures before servicing any mechanical assembly. Use a roll pin punch and hammer to drive the pin into the bore — avoid using a standard punch, as it may damage the pin's slotted profile. Ensure the bore is clean and free of debris before installation.
