LainKeen Blind Hole Collet Bearing Puller Set 13pc 8–32mm — Slide Hammer & Alloy Steel Extractor

This compact extractor kit gives technicians and DIY mechanics a practical way to pull stubborn internal bearings without cutting or destroying surrounding components. The set includes eight collets sized to fit blind bores from 8mm to 32mm, a slide hammer for impact extraction, and threaded adapters for secure engagement. Made from alloy steel, the components resist wear and rust so the toolkit stays serviceable in a garage or shop environment.

How does the kit engage bearings in blind holes?

The LainKeen system uses expandable collets that contract inside the inner race of a bearing so you can pull out the part from behind. Once the correct collet is chosen and seated, tightening or locking expands the collet against the inner surface, creating a secure grip for extraction.

• Choose the collet that fits the inner race diameter (8–32mm range).
• Insert the collet into the bearing's inner bore and lock it in place.
• Use the slide hammer or threaded adapter to pull the bearing straight out.

What components are included and what materials are they made from?

The kit includes 8 expandable collets, a slide hammer, threaded screw adapter, and a blow-molded storage case to keep parts organized. All metal parts are manufactured from high-quality alloy steel for strength, surface durability, and rust resistance.

• Eight collets covering blind hole sizes between 8mm and 32mm.
• Heavy-duty slide hammer for impact extraction with an ergonomic grip.
• Threaded adapters to interface collets with the hammer and fasten securely.
• Blow-molded case for neat storage and portability.

How do I use the slide hammer vs. the countersink (threaded) method?

The slide hammer is designed for faster, impact-style extraction when parts are moderately seized, while the countersink/threaded tightening method gives you controlled, gradual removal for delicate or stubborn bearings. Use the hammer for quick knock-outs and the tightened adapter when there’s a risk of damaging the race or surrounding components.

• Slide hammer: fit collet, attach hammer, deliver steady pulls until the bearing releases.
• Countersink/threaded: slowly tighten the adapter to push the bearing out with controlled force.
• Always confirm correct collet seating to avoid slippage or part damage.

Who is this for? This LainKeen extractor set is made for automotive technicians, motorcycle mechanics, restoration hobbyists, and home mechanics who need a reliable way to remove internal bearings and bushings from blind bores. It works well for wheel bearings, hub bearings, and press-fit bushings on cars, motorcycles, ATVs, small trucks and machinery where access is limited, offering an organized kit that reduces the need for improvised extraction methods.
