Bearing Puller Three-Arm 1" NEO tools 11-868

Three-arm bearing puller 1" NEO tools 11-868 is a mechanical extraction tool designed for removing bearings, gears and pulleys from shafts. The three-arm arrangement gives a balanced, coaxial pull that reduces the risk of damage to housings and shafts while allowing controlled removal of press-fit components. The tool is intended for workshop and maintenance environments where precise, even force application is required.

Advantages

The three-arm design ensures uniform force distribution around the workpiece, improving stability during extraction. A 1" (inch) arm spread accommodates a range of component sizes while maintaining a secure grip. Constructed for repeated workshop use, the tool enables controlled, coaxial removal which helps protect bearing seats and shaft surfaces. Its configuration simplifies setup and reduces the need for improvised methods that can cause part deformation.

Suitable for

• Removing bearings from shafts in automotive and industrial maintenance
• Extracting gears, pulleys and couplings from shafts
• Workshop repair, refurbishment and assembly tasks requiring coaxial withdrawal

Key specifications

• Arm configuration: three-arm puller for coaxial extraction
• Maximum arm spread: 1 inch (approx. 25.4 mm)
• Application: manual mechanical extraction of press-fit components
• Typical use environment: workshop and maintenance settings

How to use

Position the puller so the three arms engage behind the component to be removed, ensuring the arms sit evenly around the circumference. Center the forcing screw on the shaft end or bearing seat and begin tightening the screw evenly to apply coaxial force. Continue applying steady pressure until the component is released; avoid sudden or uneven force to prevent damage. After extraction, loosen the forcing screw and remove the arms from the component.

Usage recommendations

Use appropriate personal protective equipment and ensure the workpiece is properly supported. If a component is heavily corroded or seized, consider applying penetrating lubricant and allow time to penetrate before attempting extraction. Avoid excessive torque on the forcing screw; if higher force is required, use a puller rated for greater capacity.
