MateAuto 12pc Blind Hole Collet Bearing Puller Kit 8–32mm — 360mm Slide Hammer, Carbon Steel

MateAuto's 12-piece blind hole collet bearing puller set is a compact kit that removes recessed internal bearings and sleeves from 8–32 mm using expandable collets and a 360 mm slide hammer.

This professional-grade internal bearing puller kit is built for mechanics and DIYers who need a reliable way to extract blind (recessed) bearings without damaging housings or shafts. The set contains eight collets that expand to grip the inner diameter of bearings, a heavy-duty slide hammer for controlled impact extraction, and a molded storage case to keep parts organized. Components are forged from carbon steel for strength and wear resistance, and the kit ships with simple instructions so first-time users can get started quickly.

How does the expandable collet system secure bearings for removal?

The collets are tapered so they compress into the bearing ID and then expand when pulled back to create a positive grip. This internal expansion prevents slippage and centers the pull force, reducing the risk of damage to housings or shafts.

• Eight collet sizes covering 8–32 mm inner diameters
• Tapered design for reliable radial expansion
• Quick interchange between collets for different jobs

What kinds of vehicles and parts can this puller handle?

The kit suits a wide range of light and medium automotive and motorcycle tasks, including wheel bearings, bushings, seals, and sleeves seated in gearboxes or hubs. Its size range makes it especially useful for motorcycles, small cars, and other compact assemblies.

• Motorcycle wheel and gearbox bearings
• Small car hubs and transmission sleeves
• Compact mechanical assemblies with recessed bearings

How do you use the slide hammer with the collets safely and effectively?

Attach the chosen collet to the centering adapter, insert into the bearing, then draw the collet back so it expands and locks. Fit the slide hammer to the assembly and deliver straight, controlled pulls until the part clears the bore.

• Assemble collet and adapter, then expand inside the bearing
• Keep the hammer stroke aligned with the bore for straight pulling
• Use steady, measured impacts to avoid sudden jolts

What materials and storage options are included with the kit?

All metal parts are made from hardened carbon steel for improved durability under repeated impacts. The set comes in a molded plastic carrying case that keeps collets and accessories sorted and protected from shop debris.

• Carbon steel construction for high hardness and wear resistance
• 360 mm (1.2 ft) slide hammer for sufficient extraction force
• Sturdy plastic case for transport and storage

Who is this for: This MateAuto puller set is designed for professional mechanics, home garage enthusiasts, and motorcycle restorers who need a compact, versatile tool to remove blind bearings and sleeves without machining or damaging the housing. If you work on motorcycles, compact cars, or other small assemblies and want a reusable, portable solution for internal extractions, this kit delivers the essential collets, adapters, and slide hammer you need.
