This bearing puller is a blend of our expanding pullers and our wind-out pullers.

• Like our expanding pullers, this tool can remove blind and back-to-back bearings. 
• Like our windout puller, this tool doesn't need a hammer, instead, tightening the nut draws the bearing into a cup in a controlled manner.

This tool is suitable for many frame and hub applications, and particularly freehubs, where back-to-back bearings make our usual wind-out puller unsuitable, but the small size of the freehub makes it awkward to support the part while using our usual expanding puller.

• Each puller is engraved with it's size for easy identification
• Designed & manufactured in the UK

Compatibility

A flat area is needed around the outside of the bearing for the tool's 'cup' to rest on.  The ID of the cup is sized to give 1mm clearance around the bearing while the OD of the cup generally extends to 5mm from the edge of the bearing.  If anything protrudes within this zone our expanding pullers would be a better option.

A hole is needed through to the otherside of the part, through which a hex key can be inserted.  Through holes nearly always exist on back-to-back bearings on bicycles, but not in some less common applications, like motor cases.

How to Use

This tool is easy to use.  The method is illustrated on a freehub below.

First, the expanding collet is inserted into the bearing and the nut tightened, causing the collet to grip the inside of the bearing:

Next, the 'cup' part of the tool is placed over the collet and a nut screwed onto the end of the threaded rod.

By inserting a hex key the expanding collet can be prevented from turning while tightening the nut with a spanner.  Tightening the nut draws the expanding collet into the cup:

Our tools can be selected either by the bearing size or by the bearing's standard reference code.

Standard references take the form of a three or four digit number, such as 688, or 6902 for example. These codes are often moulded onto the bearing's seal. You might see something like 6902-2RS on the seal. The first digits are the standard reference.  The second part (2RS in this case) refers to the seal type and doesn't matter for tool selection.

Alternatively, tools can be selected by their inside (ID) and outside (OD) diameters and width.

Note that each tool is specific to one bearing size and can’t be used on bearings with different dimensions.
