Over-axle bearing press tool for mountain bike and road bike wheel hubs

This tool is designed to install the sealed cartridge bearings that are found on many brands of bicycle hub. This version of our press is designed to fit over the axles that protrude through the centre of the bearings on many hub designs, such as Hope and DT Swiss.
If the axle protrudes through the bearing, and the axle can't be removed before removing the bearing, then this press is a better choice than our regular press.
The tool consists of a set of drifts (sometimes called spacers or bushings) machined to closely match the diameter of the axle and the bearing’s outside diameter, and a threaded rod to pull the spacers together. The long drift is long enough to be used on the long drive-side of the hub's axle.
Some sizes come as combos; i.e., 6903 is only available in combination with 6803. The reason for this is that the 6903 uses a 6803 press together with an adaptor ring to match the larger outside diameter of 6903.
Each set of spacers can be purchased with either T-bar handles or simple nuts. Both of these options include the spacers and threaded rod. The T-bar handles make the tool super-easy to use, while the nuts are a functional and cheaper option and are used with normal spanners. The spacer and handles are compatible with all of our other bearing presses.
The tool is shaped to press the outer race of the bearing, meaning that no stress is placed across the bearings, prolonging bearing life and protecting the hub.
Specifically designed for bearings that have to be pressed over an axle
Bearing are installed straight, kind to hub

Unlike some other bearing press designs, this design closely fits the bearing’s outside diameter and hub axle diameter to ensure that the tool remains accurately centred and the bearings are pressed in straight.
How To Use
The press tool is simple to use:
Install the bearings and axle loosely. Slide the small 'tube' drift over the short end of the axle together with and necessary adaptor ring required to match the outside diameter of the bearing. Slide the longer 'tube' drift together with any necessary adaptor ring over the other end of the axle.
Slide the threaded rod through the centre of the axle. Tightening the nuts or handles draws the spacers together, pressing the bearing into place.
We prefer pressing in one side at a time. The hub axle can be inserted through the first bearing and the spare drift inserted in place of the second bearing to keep everything aligned.
If the bore through the axles less than 8mm (usually just the case with QR hubs), the threaded rod cannot be used. However, the spacers can still be used to tap the bearing in with a hammer.

Ourtools 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.
