Armature Bearing Puller: Controlled Bearing Removal for Motors & Power Tools

What is the armature bearing puller used for?

This puller is commonly used in motor repair, power tool servicing, and general mechanical maintenance where bearings must be removed cleanly. It helps technicians reduce downtime and avoid damage that can occur with improvised removal methods.

Common applications

• Electric motor repair: removing bearings from armature shafts
• Power tool servicing: grinders, drills, and other rotating equipment
• Workshops & maintenance teams: routine bearing replacement
• Mechanical overhaul: controlled disassembly of tight-fit parts

How do you choose the right size bearing puller?

Choose based on the bearing’s outside diameter and the clearance available around the bearing. Using the correct size ensures a secure grip and helps keep the pulling force aligned for cleaner removal.

Size guide

• 1# (19–35mm): smaller bearings and compact armature assemblies
• 2# (24–55mm): larger bearings or applications needing wider capacity

How to use an armature bearing puller safely

Correct alignment and steady pressure are the keys to safe bearing removal. Avoid sudden force, and ensure the puller jaws are seated evenly before tightening.

Best-practice steps

1. Secure the part: Clamp the armature/assembly so it can’t slip.
2. Seat the puller jaws: Ensure an even, solid grip behind the bearing.
3. Align the screw: Keep the forcing screw centered on the shaft.
4. Tighten gradually: Apply steady turns and monitor movement.
5. Release and inspect: After removal, check the shaft and bearing seat for scoring.
