LainKeen 13pcs Blind Hole Collet Bearing Puller Set - Internal

In this review of the LainKeen 13pcs Blind Hole Collet Bearing Puller Set the bottom line is simple: it is a practical, compact internal bearing extractor for technicians and hobbyists who need a reliable way to remove bearings from recesses. The kit stands out because of its expandable collet system and a 1.2 ft slide hammer that together save time on small to medium pull jobs. For anyone who works on bicycle wheel bearings, pilot bearings, or internal sleeves, this set offers a straightforward solution without complicated setup.

Key Features

• Expanded collet range: The kit includes 10 expandable collets covering 8 to 32 mm so users can match the collet to the bore for a secure internal grip.
• Added small sizes: Two 8 mm and two 10 mm collets are included in the upgraded version to cover smaller bearing jobs that earlier kits missed.
• Sturdy construction: Made of high quality carbon steel with high hardness and wear resistance for repeated use on bearings and sleeves.
• Slide hammer reach: The 1.2 ft (360 mm) slide hammer gives enough travel for positive extraction force on stuck parts.
• Internal pull design: The collets expand inside the recess so parts can be removed cleanly without damaging surrounding surfaces.

Who It's For

The LainKeen puller set is well suited to bicycle mechanics, small engine or automotive hobbyists, and workshop technicians who frequently remove pilot bearings, wheel bearings, or internal sleeves from housings. Its range of collets and a mid-length slide hammer make it particularly useful for small to medium diameter internal extractions where access is limited.

This set is less appropriate for heavy industrial use or very large bearings beyond 32 mm, and shops that require power-operated extractors for repeated heavy-duty work should look for larger commercial pullers. For occasional to regular light- and medium-duty internal pull tasks, this kit is a practical choice.

Pros & Cons

Pros

• Expandable collets cover a broad 8 to 32 mm range for versatile internal pulls.
• Solid carbon steel construction gives good durability for repeated jobs.
• Slide hammer length and design make removal quick and time saving for many users.

Cons

• Not intended for large industrial bearings beyond the 32 mm range.
• Users handling heavy or frequent shop extractions may prefer a powered or larger manual puller.

Frequently Asked Questions

Can this kit remove bicycle wheel bearings?
Yes, customers report it is effective for bicycle wheel bearings and similar small internal bearings when the correct collet size is used.

What is the largest bearing size it handles?
The expandable collets cover up to 32 mm, so bearings or sleeves larger than that are outside the kit's intended range.

Is the slide hammer long enough for tight recesses?
The 1.2 ft (360 mm) slide hammer provides substantial travel for most small- and medium-depth internal pulls, making extractions easier than short-handled alternatives.
