Bridgeport 11182083 Motor Shaft Spring Milling Machine

Product Description

The BRIDGEPORT 11182083 is a motor shaft spring designed as a direct replacement component for Bridgeport milling machines. This spring maintains proper tension on the motor shaft assembly within the 2J-Head top housing, ensuring consistent spindle engagement and reliable machine operation. It is a precise OEM-style part intended for installation by qualified machine tool technicians or millwrights performing preventive maintenance or mechanical repair on milling equipment. Replacement of worn or broken shaft springs restores correct drive function and prevents premature wear on adjacent components.

This motor shaft spring is used in the top housing of the 2J-Head configuration found on I Series Bridgeport milling machines. It is a common service part in machine shops, tool rooms, and manufacturing facilities where Bridgeport knee mills are in regular production use. Technicians typically replace this component during scheduled spindle service intervals or when diagnosing inconsistent spindle engagement, vibration, or drive slippage.
