Three-arm bearing puller MEGA model 29734, 300 x 180 mm, three-jaw extractor

Three-arm bearing puller MEGA model 29734, 300 x 180 mm, is a mechanical three-jaw extractor designed for controlled axial removal of bearings, gears and pulleys from shafts. The tool features adjustable arms that provide a secure, even grip around the component, enabling steady force application and reducing the risk of damage to the part or shaft. Constructed for workshop and maintenance use, the puller fits a range of shaft and component sizes within its 300 x 180 mm span.

Advantages

The three-jaw configuration ensures balanced pressure during extraction, improving stability and reducing slippage. Adjustable arms allow adaptation to different diameters and profiles, while the robust central forcing screw delivers reliable axial force for efficient removal. The design facilitates safer, more precise disassembly compared with improvised removal methods, making the puller suitable for repeated professional use.

Suitable for

• Removing bearings from shafts in automotive and industrial maintenance
• Extracting gears and pulleys during equipment repair
• Workshop overhaul and routine machinery servicing
• Controlled axial extraction where even force distribution is required

Key specifications

• Type: three-arm (three-jaw) mechanical puller
• Arm span / working range: 300 x 180 mm
• Intended use: axial extraction of bearings, gears and pulleys
• Adjustment: adjustable arms for varied diameters
• Operation: central forcing screw for axial force application
• Typical environment: workshop and maintenance settings

How to use

Select an appropriate arm position to fit around the component to be removed, ensure the jaws engage securely behind the part, and center the forcing screw on the shaft end or pilot point. Turn the central screw gradually using a suitable wrench or socket, applying steady axial pressure until the component slides off the shaft. Inspect the contact points during operation to confirm even engagement and stop if excessive resistance or misalignment occurs.

Usage recommendations

Before use, clean the component and shaft area to remove dirt and corrosion. Use appropriate personal protective equipment and apply penetrating oil if parts are seized. Do not exceed the puller’s capacity or attempt to use the tool on components outside its arm span. Store the puller in a dry place to prevent corrosion and inspect threads and jaws regularly for wear.
