## Summary description

Inertia hammer Rockforce RF-664B designed for bearing removal; supplied as a set with 16 interchangeable arms. The tool uses inertia impact to release press-fitted bearings, bushings and similar assemblies without direct hammering on shafts. Suitable for maintenance and repair in workshops, automotive service and industrial equipment disassembly where controlled pulling force and adaptability to different bearing sizes are required.

## Long description

The Inertia Hammer for Bearing Removal Rockforce RF-664B with 16 Interchangeable Arms Set is a specialist puller accessory designed to extract press-fitted bearings, bushings and similar interference-fit components using inertia impact. The tool converts a quick sliding mass movement into a concentrated pulling impulse, allowing removal without striking shafts directly. Supplied as a set with a range of adapter arms, the Rockforce RF-664B set adapts to multiple bearing sizes and configurations commonly found in automotive, industrial and workshop maintenance tasks.
Advantages
The inertia hammer set provides controlled impact pulling that reduces risk of damage to shafts and housings compared with direct hammering. Sixteen interchangeable arms offer broad compatibility across different bearing diameters and seating geometries, improving versatility and reducing the need for multiple dedicated pullers. The compact hand-held design enables operation in confined spaces and supports repeatable, consistent pulling force through a simple sliding action.
Suitable for
 Removal of press-fitted bearings and bushings in automotive wheel hubs and gearboxes
 Maintenance and disassembly of industrial motors and pumps
 Workshop repair tasks where controlled non-destructive extraction is required
 Situations with limited access where conventional pullers cannot be positioned
Key specifications
 Operating principle: inertia impact for pulling of press-fitted parts
 Adapter set: 16 interchangeable arms to match a wide range of diameters and seating types
 Construction: hardened steel components for durability under repeated impacts
 Form factor: compact portable hand tool suitable for confined spaces
 Compatibility: designed for use on bearings, bushings and similar interference-fit parts
How to use
Select and fit the appropriate interchangeable arm(s) to engage behind the bearing or bushing flange, ensuring correct seating and balanced contact. Position the inertia hammer so that the sliding mass moves along the tool axis and the pulling arm is aligned with the component to be removed. Deliver a series of controlled sliding impacts by accelerating and releasing the sliding mass; inspect progress between impacts and reposition arms if necessary. After extraction, check the shaft and housing for damage and clean mating surfaces before installing replacement components.
Usage recommendations
Use appropriate personal protective equipment and secure the workpiece before operating. Confirm that the selected arm provides firm engagement behind the part to avoid slippage. For tight or corroded assemblies, apply suitable penetrating lubricant and allow dwell time before attempting removal. Do not use the tool on components with cracks or where structural integrity is compromised.
