XIIW Bearing Puller Kit 2" 3" 4" 6" — 2-Jaw Adjustable Chrome Vanadium Set

The XIIW 4 Bearing Puller Kit is a durable, adjustable two-jaw tool set designed to extract bearings, gears and pulleys from 2", 3", 4" and 6" diameters with precision and safety.

This professional-grade puller kit provides a compact solution for mechanics, hobbyists and maintenance technicians who need to remove flywheels, wheel bearings, rotors and pulleys without damaging surrounding components. Made from hardened chrome vanadium steel with heat-treated mandrels and secure hex fastenings, the set balances strength with adjustability so you can handle a wide range of repair jobs using the same two-jaw configuration.

How does the XIIW puller adapt to different bearing and gear sizes?

The puller’s jaws and mandrel rotate to open or close, letting you set the clamping depth for a snug fit on varying diameters. Four included sizes cover most light- to medium-duty applications, while the two-jaw design keeps force centered for cleaner extractions.

• Sizes: 2" (35×45 mm), 3" (38×65 mm), 4" (40×80 mm), 6" (55×90 mm)
• Adjustable jaw spacing via reversible rotation
• Heat-treated mandrel for consistent pressure transmission
• Two-jaw geometry for symmetric pulling force

Is the kit strong enough for automotive or motorcycle work?

Yes — components are forged from chrome vanadium steel, giving higher hardness and fatigue resistance than standard carbon steel. The threading and hex screw locking system reduces slippage, so the tool holds under high extraction loads common in automotive and motorcycle tasks.

• Chrome vanadium construction for durability
• Hexagonal screw with coarse thread prevents dropping
• Heat-treated mandrel resists bending under torque
• Suitable for flywheels, rotors, and medium-duty wheel bearings

What safety and usability features does this kit include?

The kit emphasizes controlled extraction and secure clamping to limit accidental slippage and part damage. The anti-drop design and threaded fixing point keep jaws locked in place while you turn the central mandrel, reducing sudden releases.

• Anti-drop hex screw and thread locking for jaw security
• Reversible rotation to expand or tighten jaw grip safely
• Compact pieces for access in confined engine bays
• Two-jaw setup reduces the chance of uneven pull or part tilting

How should I choose the correct size and use the puller effectively?

Select the size whose jaw reach most closely matches the component’s inner or outer surface, then secure the jaws and tighten the mandrel evenly. Work slowly, applying steady torque and checking alignment to avoid bending or marring the part.

• Measure bearing or pulley diameter before choosing a puller size
• Fit jaws around the intended lip or flange for even clamping
• Tighten the mandrel gradually while ensuring centered pull
• Use penetrating lubricant if parts are seized to reduce shock

Who is this for: The XIIW 2-Jaw Puller Kit is aimed at DIY mechanics, motorcycle and bicycle repairers, fleet maintenance staff and small machine shops that require a rugged, versatile extractor without investing in specialized single-purpose tools. It’s especially useful when working on flywheels, rotors, gears and medium-sized bearings where a controlled, centered pull and durable construction are priorities.
