Two-arm bearing puller 350×210 mm No name model 29742

Two-arm bearing puller 350×210 mm No name model 29742 is a mechanical extraction tool designed to remove bearings, gears and pulleys from shafts with controlled force. The tool features two adjustable arms with a maximum span of 350 mm and a reach of 210 mm, operated by a central forcing screw that delivers even axial pressure to extract press-fit components without damaging surrounding parts.

Advantages

The two-arm configuration ensures symmetrical force distribution for stable and accurate removal of components. Adjustable arms accommodate a range of diameters and the 210 mm reach allows access to recessed assemblies. The central forcing screw provides gradual, controllable extraction, reducing the risk of sudden slips or part damage. Constructed for workshop and maintenance use, the puller is compact enough for handheld operation while offering sufficient leverage for most light-to-medium extraction tasks.

Suitable for

• Removing bearings from shafts in automotive repair and maintenance
• Extracting gears and pulleys during mechanical servicing
• Workshop and industrial maintenance tasks requiring controlled pull-off of press-fit parts
• General machinery repair where access depth is up to 210 mm

Key specifications

• Two-arm puller design for balanced extraction
• Maximum arm span: 350 mm
• Reach (depth): 210 mm
• Central forcing screw operation for axial force application
• Adjustable arms suitable for a variety of diameters
• Hand-operated for manual workshop use

How to use

Position the two arms behind the component to be removed so that they grip evenly around the flange or inner edge. Adjust the arm span to match the part diameter and ensure the arms are seated securely. Center the forcing screw on the shaft end and turn it progressively with a wrench or driver to apply axial force. Maintain steady pressure and check alignment frequently to prevent tilting; continue turning the screw until the bearing, gear or pulley is freed from the shaft. After extraction, retract the arms and inspect the tool and components for wear or damage.

Usage recommendations

Use appropriate personal protective equipment such as safety glasses and gloves. Select an arm position that gives full contact with the part and avoid side loading. For heavily corroded or tightly press-fit components consider applying penetrating lubricant and allow gradual, incremental force to avoid part fracture. Store the puller in a dry place and inspect the forcing screw and arm pivots regularly for thread wear or deformation.
