XIIW 4‑Piece Bearing & Pulley Puller Kit 2"–6" Adjustable — Chrome Vanadium 2‑Jaw, Hardened Jaws

The XIIW 4 Bearing Puller Kit is a two-jaw, adjustable pulley and bearing remover built from chrome vanadium steel for reliable, repeatable extraction of gears, rotors and bearings from 2" to 6" assemblies.

This compact kit gives technicians and DIYers a versatile, durable solution for extracting stuck pulleys, flywheels, and bearings without damaging surrounding parts. Each size features hardened jaws and a treated mandrel so you can apply controlled force while the anti-drop screw design keeps setup secure. The set covers common workshop needs with four puller frames and a reversible mechanism that adapts to different clamping depths.

How does the puller adjust to different bearing or pulley sizes?

The puller arms rotate to change opening width and the sliding jaws allow you to vary clamping depth, so one tool fits multiple diameters. Swap between the included 2", 3", 4" and 6" frames to match the component size and orient the jaws for internal or external pulls.

• Rotating jaw collars expand or contract the working span.
• Adjustable clamping depth handles shallow to deep-set parts.
• Four frame sizes cover 35×45mm up to 55×90mm ranges.
• Reversible jaw orientation for internal/external extraction.

Why choose chrome vanadium steel and treated mandrel construction?

Chrome vanadium offers higher tensile strength and wear resistance than standard carbon steels, so jaws and frames resist bending under load. The mandrel receives heat treatment to maintain thread integrity and reduce galling when applying torque, extending the tool’s working life under frequent use.

• Hardened chrome vanadium frames resist deformation.
• Heat-treated mandrel keeps threads true under pressure.
• Corrosion-resistant finish prolongs surface life.
• Durable materials reduce the need for replacement tools.

What safety and ease-of-use features help during extraction work?

The kit includes a hexagonal screw and secure thread lock to prevent accidental slippage of the mandrel during pulling. Non-slip contact points on the jaws and the anti-drop thread design help maintain grip on irregular parts while you apply steady torque, improving safety and control.

• Hex screw for positive wrench engagement and controlled turning.
• Anti-drop thread reduces sudden releases or slips.
• Non-slip jaw faces protect part surfaces during extraction.
• Compact frames allow work in confined spaces like engines or wheel hubs.

Which applications and parts are best suited for this kit?

This two-jaw puller set was designed to remove bearings, gears, rotors, and pulleys from automotive and light machinery applications. It is well suited for small engines, motorcycle and bicycle hubs, alternators, and similarly sized assemblies where controlled extraction is required.

• Automotive flywheels and alternator pulleys.
• Motorcycle and bicycle wheel bearings and rotors.
• Small machine wheels and gearbox components.
• General workshop maintenance and home mechanic projects.

Who is this for: The XIIW 4 Bearing Puller Kit is intended for mechanics, maintenance technicians and informed DIYers who need a compact, adjustable puller set that balances strength and precision. If you routinely remove bearings or pulleys from engines, small machines or vehicle hubs and want a durable, low-profile toolset that adapts to multiple sizes, this kit provides a practical, workshop-ready solution without buying multiple single-size pullers.
