AIUWIZO Blind Hole Bearing Puller Set — 12pc 8–32mm Slide Hammer Kit, Hardened Steel Collets

The AIUWIZO 12pcs Blind Hole Bearing Puller Set is a slide-hammer system with eight expandable collets that remove inner bearings and bushings from 8–32 mm housings quickly and cleanly.

This compact kit pairs a 360 mm (1.2 ft) slide hammer with a range of collets and pilot adapters so you can extract blind-hole bearings, sleeves and bushings from motorcycles, bicycles, ATVs, small engines and many automotive applications without cutting or welding. Built from hardened steel components, the set is made for repeated garage and shop use; proper sizing and gentle alignment deliver the best results and protect the tool and parts.

How does this puller remove blind-hole bearings safely?

The tool expands inside the bearing bore using an expandable collet that locks against the inner diameter. Once the collet is firmly seated, the slide hammer transmits controlled impact outward to pull the bearing free without damaging the housing.

• Expandable collets sized for 8–32 mm inner diameters to grip the bearing internally.
• 360 mm slide hammer provides punch force with user-controlled strikes.
• Threaded pilot and extension rods let you set depth and alignment precisely.
• Use a soft-faced hammer for minor realignment if the collet binds.

Which sizes and parts are included in the kit?

The AIUWIZO set includes eight expandable collets that cover 8 mm to 32 mm inner diameters, multiple pilot pieces and the 360 mm slide hammer assembly. The variety of pilot and collet combinations supports a wide range of bearing and bushing sizes commonly found on light vehicles and powersports equipment.

• Collet coverage: 8 mm to 32 mm (5/16"–1-1/4") inner bore sizes.
• Slide hammer length: 360 mm (1.2 ft) for strong extraction force.
• Pilots and adapters for depth control and alignment in blind bores.
• Durable steel construction for shop and field repairs.

What preparation and technique produce the best results?

Confirm the bearing inner diameter before selecting a collet and clean the bore of debris or corrosion. Thread the chosen collet and pilot together, insert and tighten until the collet expands fully inside the bearing, then use steady slide-hammer strikes to extract the part without twisting the housing.

• Measure the bearing inner diameter to select the correct collet size.
• Clear dirt, grease and loose corrosion from the bearing bore first.
• Tighten the extension rod so the collet locks securely before hammering.
• If a bearing is seized or heavily rusted, avoid forcing it; inspect and use appropriate penetrating methods or a larger tool.

Will this set work on my motorcycle or small engine?

Yes — the kit is designed for inner bearings, sleeves and bushings found in motorcycles, bicycles, ATVs, garden equipment and many passenger vehicles. Always verify the specific inner diameter and clearance before attempting removal to ensure compatibility and avoid tool or component damage.

• Common compatibility: motorcycles, scooters, bicycles, ATVs, lawn equipment and small-engine assemblies.
• Not suited for bearings with inner bores outside 8–32 mm or severely damaged housings.
• Inspect the bearing and housing for rust or seizure before use; do not exceed tool limits.
• Works best when used with steady, controlled impact and correct collet selection.

This AIUWIZO puller is for DIY mechanics, mobile technicians and garage professionals who need a reliable, reusable solution for extracting blind-hole bearings without destructive methods. If you frequently work on motorcycles, ATVs, small engines or light automotive jobs and need a compact, versatile puller set that covers a broad range of inner bore sizes, this kit provides the parts and leverage to get the job done while minimizing housing damage. Confirm bearing dimensions before purchase and follow safe removal technique for consistent, repeatable results.
