Puller MEGA two-arm bearing puller 400×230 mm model 29743

MEGA two-arm bearing puller model 29743 is a manual mechanical extractor designed for controlled axial removal of bearings, gears and pulleys from shafts. With reach dimensions of 400×230 mm, this two-arm puller provides extended reach and firm grip for workshop and maintenance applications. The tool is intended for tasks requiring evenly distributed pulling force and reliable alignment to minimise shaft or component damage.

Advantages

The two-arm design ensures balanced extraction force on opposite sides of the component, reducing the risk of tilting or jamming during removal. A robust central forcing screw transfers torque to linear pulling action, offering precise control over extraction speed and force. The long reach of 400×230 mm allows access to bearings and assemblies located deeper on shafts or within housings. The mechanical, non-powered operation makes the puller suitable for environments without compressed air or power tools while keeping maintenance simple.

Suitable for

• Removing bearings from shafts in automotive repair
• Extracting gears and pulleys in industrial maintenance
• Workshop use for machinery disassembly and reconditioning
• Controlled axial extraction where component alignment is required

Key specifications

• Tool type: two-arm mechanical bearing puller
• Reach dimensions: 400 × 230 mm (arm reach × jaw span)
• Operation: manual forcing screw for axial extraction
• Material: hardened steel components for strength and wear resistance
• Design: adjustable arms for internal or external gripping depending on setup

How to use

Select the appropriate jaw orientation and adjust the arms so the puller grips the component securely. Centre the forcing screw on the shaft end or press plate, ensuring alignment between the screw and the component axis. Turn the forcing screw steadily to apply axial force until the bearing, gear or pulley slides free. Periodically check alignment and grip during operation to avoid uneven loading; use penetrating oil if components are corroded or seized.

Usage recommendations

Use appropriate personal protective equipment, support heavy components during extraction, and avoid applying excessive torque that could damage shafts or tool threads. For press-fitted components or parts with heavy corrosion, consider controlled heating or lubrication to reduce extraction force and prevent sudden releases.
