Three-arm puller NEO tools TOP-11-857 — 6" (152 mm) puller for bearings and gears

Three-arm puller NEO tools TOP-11-857 — 6" (152 mm) puller for bearings and gears is a mechanical extraction tool designed for removing bearings, gears, pulleys and other press-fitted parts with a maximum spread of 152 mm. The three-arm configuration ensures balanced gripping and steady centring on the component, allowing controlled axial force to separate tightly fitted parts from shafts or housings. The tool is intended for workshop and maintenance use where safe extraction without damage to housings or components is required.

Advantages

The three-arm design delivers uniform force distribution around the circumference of the part, reducing the risk of misalignment or uneven prying. A 6" (152 mm) reach accommodates a wide range of bearing and gear sizes commonly found in automotive, industrial and agricultural equipment. The mechanical central forcing screw provides precise, controllable extraction force for smooth removal, while the removable and adjustable arms adapt to different attachment points and part geometries.

Suitable for

• Removing bearings from shafts and housings
• Extracting gears and pulleys from assemblies
• Workshop maintenance and mechanical repairs
• Servicing automotive, industrial and agricultural machinery

Key specifications

• Maximum spread (reach): 152 mm (6 inches)
• Three-arm configuration for balanced gripping
• Central forcing screw for axial extraction
• Adjustable/removable arms to fit varied part geometries
• Suitable for press-fitted parts such as bearings, gears and pulleys

How to use

Select and fit the puller arms so they engage securely behind the part to be removed, aligning the central forcing screw with the shaft or press-fit centre. Tighten the forcing screw evenly to apply axial force; advance the screw gradually while monitoring the part and surrounding housing to avoid sudden release. If required, reposition the arms for better engagement and continue controlled tightening until the component is freed. Use appropriate personal protective equipment and support the workpiece to prevent movement during extraction.

Usage recommendations

Before use, inspect the puller for damage, ensure the arms are correctly seated and use a suitable wrench or driver for the forcing screw. Apply steady, controlled force and avoid using excessive impact that could deform parts. For corroded or tightly seized components, apply penetrating lubricant and allow time to work before extraction. Store the tool dry and clean after use to maintain functionality.
