Bearing puller 3-arm 100 mm JOBIprofi JOBI 19784

The JOBIprofi Bearing puller 3-arm 100 mm JOBI 19784 is a mechanical three-arm puller designed to extract bearings, gears and pulleys with an even, centered force. Its 100 mm span accommodates a range of medium-sized press-fit components commonly found in automotive and workshop applications. The three-arm construction ensures balanced grip and stable alignment during removal, reducing the risk of slippage or uneven loading on the part and surrounding components.

Advantages

The three-arm configuration distributes pulling force evenly around the circumference of the part, improving stability and minimizing damage to the component. A 100 mm reach makes the tool versatile for many medium-sized bearings and accessories. The mechanical design provides direct, controlled extraction without the need for power sources, enabling use in remote or constrained workshop environments. The tool’s geometry supports centered pulling for safer, more predictable removal operations.

Suitable for

• Removing bearings from automotive hubs and housings
• Extracting gears and pulleys in engine and transmission maintenance
• Workshop machinery disassembly and repair tasks
• Situations requiring centered, controlled pulling of press-fit components

Key specifications

• Design: three-arm mechanical puller for even radial grip
• Maximum span (arm reach): 100 mm, suitable for medium-sized components
• Application: removal of bearings, gears, pulleys and similar press-fit parts
• Operation: manual mechanical extraction requiring hand actuation

How to use

Select the appropriate arm position so the jaws securely engage the component behind its lip or shoulder. Center the puller so the forcing screw aligns with the shaft or press-out point and tighten the central screw steadily to apply even pulling force. Maintain alignment during operation to prevent bending or off-axis loads. If the component is seized, apply gradual force and check for obstruction points; avoid sudden impact or excessive torque that could damage the tool or the workpiece. After removal, inspect the component and surrounding parts for wear or damage.

Usage recommendations

Use basic hand tools to support and protect adjacent surfaces when needed, and wear appropriate personal protective equipment such as safety glasses and gloves. For frozen or rusted components, consider light penetrating lubricant and incremental force rather than abrupt high torque. Store the puller in a dry place and inspect arms and threads for damage before each use.
