Bearing Puller 3-Arm 12" GEKO PROFI G02246 by GEKO

The GEKO PROFI 3-Arm Bearing Puller G02246 is a 12" mechanical puller designed for controlled extraction of bearings, gears and pulleys. Its three-arm configuration distributes force evenly around the component, enabling concentric removal with reduced risk of damage to the shaft or housing. Compact and robust, this tool is suitable for professional workshops and DIY maintenance where stable, reliable bearing removal is required.

Advantages

The three-arm design provides balanced pulling force for safe, concentric removal of rings, gears and pulleys. Mechanical screw drive allows gradual, controlled extraction without relying on hydraulic systems or external power. Constructed from hardened steel components, the puller offers durability for repeated workshop use while remaining compact enough for storage and transport. The tool is compatible with a variety of part diameters due to adjustable arm positions.

Suitable for

• Removing bearings from shafts and housings
• Extracting gears, pulleys and sprockets
• Automotive repair and maintenance tasks
• General workshop and machine maintenance

Key specifications

• Tool type: three-arm mechanical bearing puller
• Overall size: 12 inches (approx. 305 mm)
• Material: hardened steel arms and screw drive
• Operation: manual screw-driven extraction for controlled force application
• Adjustability: arms can be positioned to accommodate different diameters and grab depths

How to use

Position the puller so the three arms securely engage the back of the bearing, gear or pulley to be removed. Adjust the arm positions to obtain a uniform grip and align the screw drive with the shaft center. Turn the central screw gradually to apply steady extraction force while monitoring alignment to ensure concentric removal. If necessary, re-tighten or reposition the arms to maintain even contact during the pull. After the component is removed, back off the screw and release the arms.

Usage recommendations

Always wear appropriate personal protective equipment and ensure the workpiece is secured before applying force. Use gradual, even turns of the screw drive to avoid sudden release or part damage. For seized or corroded components, apply penetrating lubricant and allow it to act before attempting extraction. Inspect the puller for wear or damage before each use and replace any deformed parts to maintain safe operation.
