Bearing puller 3-arm 100 mm GEKO G02231

The GEKO Bearing puller 3-arm 100 mm G02231 is a mechanical three-jaw extractor designed for removing bearings, gears and pulleys with a maximum reach of 100 mm. Its three-arm configuration ensures even force distribution around the component, allowing controlled disassembly of press-fit parts in automotive, industrial maintenance and workshop environments. The tool is intended for applications that require a stable, centered pull and reduced risk of component damage during extraction.

Advantages

The three-arm design provides balanced extraction force, reducing bending or tilting of the removed part. A 100 mm reach allows access to moderately recessed components while maintaining mechanical stability. The puller’s construction offers straightforward operation for technicians and mechanics, with a compact footprint that fits typical workshop tool sets. Its mechanical operation does not require external power sources, making it suitable for on-site maintenance tasks.

Suitable for

• Removing bearings from shafts and housings
• Extracting gears and pulleys in automotive repair
• Workshop and maintenance tasks involving press-fit components
• Industrial equipment servicing where controlled disassembly is needed

Key specifications

• Tool type: Three-arm mechanical bearing puller
• Maximum reach: 100 mm
• Arm configuration: Three jaws for balanced force distribution
• Operation: Manual/mechanical (no external power)
• Typical use: Bearings, gears, pulleys and similar press-fit parts

How to use

Position the three jaws symmetrically around the component to ensure even grip. Adjust the arms so the jaws engage securely behind the inner or outer lip of the bearing, gear or pulley. Center the forcing screw on the shaft or the press-fit point and tighten gradually, maintaining alignment to avoid tilting. Apply steady, controlled force until the component is freed. If resistance is high, verify correct jaw engagement and alignment before increasing force.

Usage recommendations

Before use, inspect the puller for wear or deformation and ensure the jaws are clean and undamaged. Use appropriate personal protective equipment such as safety glasses and gloves. For seized or corroded components, consider applying penetrating lubricant and allowing it to act before extraction. If higher extraction force is required, use appropriate supporting equipment or seek assistance to prevent tool overload and component damage.
