LainKeen Blind Hole Bearing Puller Set — 12pc 8–32mm Kit with Slide Hammer & Hardened Collets

LainKeen's 12-piece blind hole bearing puller set removes internal bearings and bushings from 8mm to 32mm blind bores without damaging surrounding parts.

Designed for motorcycle, car and light-truck maintenance, this compact kit pairs hardened alloy collets with a slide hammer and threaded adapters to extract seized or recessed bearings from blind holes. The set is organized in a blow-molded case for quick selection and secure storage, helping both home mechanics and professional technicians complete bearing removal tasks faster and cleaner.

How does the kit remove bearings from blind holes?

The system uses expanding collets that lock into the inner race of a bearing; once engaged, pulling force is applied either by a sliding weight or by tightening the threaded adapter for controlled extraction. That combination lets you pull bearings that have no external lip to grab, reducing the need for welding or destructive removal methods.

• Expanding collets lock inside the inner race for a secure grip.
• Slide hammer delivers impact force for quick ejection.
• Threaded adapter allows gradual, controlled removal when needed.
• Range covers 8mm–32mm blind hole diameters with eight collet sizes.

What materials and build quality can I expect?

Each component is manufactured from high-quality alloy steel that is heat-treated for strength and wear resistance. Surfaces are finished to resist corrosion and maintain a precise fit between collet jaws and adapters, extending tool life under heavy workshop use.

• Hardened alloy-steel collets and adapters for durability.
• Fine workmanship on threads and mating surfaces for reliable engagement.
• Rust-resistant finish to reduce maintenance needs.

How do I use the set safely without harming the wheel or hub?

Choose the correct collet for the bearing ID, insert and expand it inside the race to seat firmly, then use the slide hammer or tighten the adapter to remove the bearing. Using the slide hammer is faster for loose or lightly seized bearings; the threaded adapter provides controlled pressure for tight fits or fragile components.

• Match collet size to the bearing inner diameter for secure engagement.
• Use the slide hammer for impact extraction; use adapter tightening for gradual removal.
• Support the hub assembly to prevent bending or scoring during extraction.
• Wear eye protection and gloves; check surrounding components for damage before reassembly.

What comes in the kit and how is it organized?

The kit contains eight collets covering blind-hole sizes from 8mm to 32mm, a slide hammer, threaded screw adapter components, and a molded case that keeps each piece in place. That organization speeds selection on the bench or roadside and protects the tools during transport.

• 12 total pieces: eight expanding collets plus slide hammer and adapters.
• Blow-molded carrying case with labeled slots for each part.
• Compact footprint fits most toolboxes and shop drawers.

Who is this for: The LainKeen blind hole bearing puller set is aimed at motorcycle mechanics, DIY riders, automotive technicians, and restoration hobbyists who need a reliable, non-destructive way to extract internal bearings and bushings. It is suitable for occasional home use and regular shop work where blind bore sizes fall between 8mm and 32mm and a durable, portable kit is preferred.
