Product Information
Full details
This Sealey Blind Bearing Puller Set (AK714) is designed for mechanics and DIY enthusiasts needing to remove bearings from blind housings. Its key benefit is providing a secure and effective grip on a range of internal bearing diameters using its specialized collets and slide hammer. A potential caveat is that the medium stroke slide hammer may require significant force for very stubborn or large bearings.

FAQs
What is the maximum bearing size this set can handle?
The set includes four collets with internal capacities ranging from 11mm to 32mm. The largest collet is designed for bearings with an internal diameter of 25-32mm.
Can this set be used for external bearing removal?
No, this set is specifically designed as a *blind* bearing puller, meaning it is for removing bearings from housings where only internal access is available. It grips the inner diameter of the bearing.
What material are the collets made from?
The collets are part of a set designed for bearing extraction and are typically made from hardened steel to withstand the forces involved.
How should I clean the slide hammer?
Wipe the slide hammer clean with a dry cloth after each use. For stubborn grime, use a damp cloth and dry thoroughly. A light application of oil can prevent rust on the shaft.
What is the weight and length of the slide hammer?
The medium stroke slide hammer has an overall length of 380mm and a hammer weight of 0.85kg.
Is this tool suitable for automotive applications?
Yes, this tool is suitable for removing various bearings found in automotive components such as wheel hubs, alternators, and other auxiliary systems where bearings are pressed into blind housings.
How do I store the set to prevent damage?
The set is supplied in a dedicated storage case. Always return the collets and slide hammer to their designated spots within the case after use to protect them from damage and ensure they remain organized.
Troubleshooting
Collet does not grip the bearing securely
Ensure you have selected the collet with the closest internal diameter match to the bearing. For slightly looser fits, try a different collet or ensure the collet is fully seated against the bearing's inner race.
Slide hammer impact is not removing the bearing
Verify the collet is properly engaged. For stubborn bearings, try gently rotating the collet slightly after engagement to break any corrosion seal. Consider using a penetrating lubricant around the bearing seat and allow it to soak before re-attempting extraction. For very large or seized bearings, a more powerful slide hammer might be required.
Collet appears to be expanding or deforming
Cease operation immediately. The selected collet may be too large for the bearing or the bearing is excessively seized. Check for damage on the collet and consider using a different, appropriately sized collet. Do not force a collet that is not a correct fit.
Pros and Cons
Pros
- Versatile range of collet sizes for common bearings.
- Durable construction from chromed carbon steel.
- Includes a slide hammer for direct impact application.
- Comes with a storage case for organization and transport.
Cons
- Medium stroke slide hammer may be insufficient for extremely seized bearings.
- Requires manual application, potentially time-consuming for multiple removals.
- Collet sizes are specific; may not fit non-standard or very small/large bearings outside the range.
Setup, Compatibility & Care
Setup:
- Select the appropriate collet for the bearing size. Ensure the collet's internal diameter is a snug fit against the inner diameter of the bearing.
- Insert the selected collet into the bearing housing, ensuring it grips the inner race of the bearing.
- Attach the slide hammer to the collet.
- Use the slide hammer by pulling the weight back and then striking it forward to create an impact.
Compatibility: This set is designed for bearings with internal diameters ranging from 11mm to 32mm. It is most effective when the collet can grip the *internal* diameter of the bearing race. It is not suitable for bearings with external diameters that exceed the capacity of the collets or for bearings where external access is available.
Care:
- After use, clean the collets and slide hammer to remove any dirt or debris.
- Apply a light coating of oil to metal parts to prevent rust, especially if stored for extended periods.
- Store all components securely in the provided case to prevent loss or damage.
