Rear End Arbor Bearing for Radial Arm Saw

The rear end arbor bearing for Radial Arm Saw motors is a replacement part that supports smooth motor rotation on Original Saw Radial Arm Saws. Built to electric motor quality standards, this bearing helps maintain performance, reduce vibration, and protect the internal components of your saw’s motor.

Engineered for the Rear of the Motor

This bearing supports the rotor shaft from the back of the motor assembly. When a rear end arbor bearing begins to wear, symptoms may include increased noise, slowing motor speed, heat at the motor housing, or subtle vibration during cutting. Replacing a failing rear bearing restores stability and helps prevent damage to the motor windings or shaft.

Ideal for Motor Rebuilds and Routine Service

Many users replace both the front end bearing and rear bearing at the same time, especially during brake service or a complete motor tear-down. Incorporating this bearing into your preventative maintenance schedule helps extend the motor’s lifespan and keeps the saw operating reliably in high-demand environments.

Installation Overview

To access the rear end arbor bearing, the rear portion of the motor must be disassembled, including removal of the end bell, fan, fan cover, and brake components where applicable. Once these parts are removed, the rotor assembly can be serviced and the bearing replaced during a complete motor inspection.

Compatibility

• Fits all current Original Saw Contractor Duty and Heavy Duty Radial Arm Saws

Note: Rear bearing is specific to several radial arm saw series motors and is not used on beam saws.
