Siapupy 12-piece Blind Hole Collet Bearing Puller Set with 360mm Slide Hammer — 8–32mm Expandable Collets, Heat-Treated Steel

Siapupy's 12-piece blind hole collet bearing puller set pairs eight expandable collets (8–32mm) with a 360mm slide hammer to remove bearings, bushings and sleeves from blind or recessed holes without needing extra adapters.

This compact kit is built for mechanics, hobbyists and technicians who need a reliable internal bearing puller that works across a wide range of sizes. Every component is precision-machined from heat-treated steel for consistent strength and wear resistance. The collets expand inside the part to create a secure, non-slip grip and the heavy slide hammer delivers controlled extraction force so you can remove parts cleanly from blind or recessed bores.

How does this set extract bearings from blind holes?

The collets expand inside the inner diameter of the bearing or sleeve to form a tight internal grip, eliminating the need to access the backside. Once engaged, the 360mm slide hammer transfers straight, repeatable pulling force to extract the component from the recess without relying on surrounding surfaces.

• Expandable collets (8 sizes) conform to inner diameters for secure hold
• Threaded adapters connect collets to the slide hammer for direct pull
• 360mm slide hammer provides sufficient leverage for stubborn parts
• Works in blind or recessed bores where external jaws can't reach

What materials and construction ensure durability?

All parts are made from high-grade, heat-treated steel and precision-machined to tight tolerances. That combination gives the kit long service life, resists deformation under impact and keeps threads and gripping surfaces reliable through repeated use.

• Heat-treated steel retards wear and bending under load
• Machined contact surfaces maintain consistent collet expansion
• Robust slide hammer shaft and head for repeated striking
• Protective plastic case prevents corrosion and damage in transport

Which tasks and vehicles is this tool best suited for?

The Siapupy puller is engineered for removing internal bearings, pilot bearings, bushings and sleeves from cars, motorcycles, ATVs and light machinery. Its size range and compact case make it a good fit for workshop benches, mobile repair kits and home garages.

• Motorcycle and scooter wheel and pilot bearing removal
• Automotive blind-hole bearings and bushings in tight engine or gearbox spaces
• Small machinery and equipment maintenance where access is limited
• Field service use thanks to the lightweight, organized carrying case

Who is this for: The Siapupy 12-piece blind hole collet bearing puller set is ideal for professional mechanics, mobile technicians, restoration enthusiasts and DIYers who need a compact, durable internal puller capable of handling 8–32mm inner diameters. If you frequently remove bearings or sleeves from recessed bores and want a single kit that reduces the need for multiple adapters, this set offers a practical blend of range, strength and portability without making you assemble extra tooling on the spot.
