Our 'expanding type' pullers are an effective way of removing stuck outer bearing races after a bearing has split apart.

Bearings can split during removal for a variety of reasons; if the balls inside the bearing are excessively corroded or worn, or if the inner race is cracked, then failure is possible.  Angular contact bearings, historically favoured by some brands such as Santa Cruz, are very strong in the direction that they are pressed into the frame but very weak in the direction of removal, and frequently split. 

When a bearing splits apart it can be difficult to remove the remaining outer race from the frame or hub.  The traditional methods are either to tap out the race with a screwdriver or to grind out the race with a Dremel.  Both of these options risk damage to the frame or hub.

Our expanding pullers offer an easy and safe way to grip the remaining outer race.  The tool and the race can then be brought out together by tapping on the tool with a drift, in just the same way that our tools are used to remove a complete bearing. 
 

How To

The process below illustrates the removal of a complete bearing but the process is exactly the same for the removal of a stuck outer race - the only difference is in the size of tool selected.

The bearing puller tool is simple to use. As well as the puller you will need a pair of spanners (or one spanner and a set of pliers), a hammer and a rod/drift/old bolt

• Insert the circular end of the tool into the centre of the bearing.  Grip the hexagonal body of the tool with a spanner or pliers and tighten the nut. This will expand the tool, gripping the bearing
• With the hub/frame supported on a bench or block of wood, the bearing and tool can be tapped out together by simply insert a rod/drift/old bolt into the other side of the bearing and tapping the end of the rod with a hammer

See our Manuals page to download the more detailed instruction sheets which come with our puller orders, now available in several languages.

Here's a quick demo of the tool's use on a hub:

Note that each tool is specific to one bearing size. It is designed to match the internal diameters and width of the bearing and can't be used on bearings of different size

Bearing Presses

We offer a comprehensive range of bearing presses, available in all of the same sizes and kits as our bearing pullers.  We offer 30% off every second item bought from our single tools menus, including mixes of pullers and presses

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.
