Bearing puller 3-arm GEKO G30300, removable jaws, 12–38 mm reach

The GEKO 3-arm bearing puller G30300 is a compact, three-jaw tool designed for removing bearings, gears and pulleys from shafts and housings. With a working reach of 12–38 mm the puller covers a range of small to medium components commonly encountered in workshop, automotive and light industrial maintenance. The removable arms and central forcing screw provide controlled, concentric extraction while reducing the risk of damage to the part or surrounding assembly.

Advantages

This three-arm design ensures even distribution of pulling force for stable, concentric removal. Removable jaws allow the tool to be configured for different extraction profiles and to access components in confined spaces. The central forcing screw gives precise control over extraction speed and force, improving safety and reducing the chance of slippage. The compact size and adjustable reach make the tool versatile for varied maintenance tasks.

Suitable for

• Removing bearings from shafts and housings
• Extracting gears and pulleys in automotive repair
• Maintenance and disassembly of small electric motors and gearboxes
• Workshop and light industrial mechanical repairs

Key specifications

• Arm configuration: three removable arms for even gripping
• Working reach: 12–38 mm
• Application: internal and external extraction of bearings, gears, pulleys
• Operation: central forcing screw for controlled axial force
• Material: hardened steel components for durability (manufacturer-standard finishing)
• Size class: compact, suitable for small-to-medium components

How to use

Select and fit the appropriate removable arms to match the component profile and position the arms evenly around the part. Tighten the clamping points so that the arms securely engage the edge of the bearing, gear or pulley. Align the central forcing screw with the shaft or extraction point and rotate the screw evenly to apply axial force; continue until the component is released. Inspect the part and surrounding components after removal and clean the tool before storage.

Usage recommendations

Use appropriate personal protective equipment and ensure the workpiece is securely supported before extraction. Avoid applying excessive lateral force to the arms; keep the pulling force axial and steady. For rusted or seized parts, apply penetrating lubricant and allow time for penetration before using the puller. Store the removable arms and screw in a dry place to prevent corrosion.
