Press for bearings with an extended inner race

While on most bearings the inner and outer races are the same width (the bering is 'flat'), some bearings feature an inner race that protrudes by a mm or two from the rest of the bearing.

It is always important to install a bearing by pressing on the outer race rather than the inner race.  These special drifts feature a recess machined in the face so that the inner race of an extended bearing isn't in contact with the drift.

Designed to install the sealed cartridge bearings that are found on many brands of full suspension MTB bike frames. Each tool consists of a pair of drifts (sometimes called spacers or bushings) precision machined to match the bearings inside and outside diameters, and a threaded rod to press the drifts together.

• Designed & manufactured in the UK
  
• Precision engineered from 316L stainless steel and 6082-T6 aluminium
• Wide range of sizes available
• Bearings are installed straight, kind to frame or hub

Each press can be purchased with either T-bar handles or simple nuts. Both of these options include a pair of drifts and one of our new precision-engineered stainless steel threaded rods.  The same threaded rod and handles can be used with these 'extended' drifts and our regular drifts.

The T-bar handles make the tool super-easy to use, and come with a pair of extensions for added versatility, while the nuts are a functional and cheaper option and are used with normal spanners.

A 'drifts only' option is offered for buyers who have already purchased the kit with the T-bar handles or the nuts before, and only need the drifts to fit a bearing size.

The threaded portion of the threaded rod supplied with this press is 144mm long with additional 8mm of non-threaded length at each end to lead the handles/nuts on and off.

All of our presses are designed around an 8mm threaded rod, but if you already have a press from another manufacturer that uses a different diameter, we can bore out our drifts to match at no additional cost.  Just drop us an email. 

Unlike some other bearing press designs, our design closely fits the inside and outside diameters of the bearing to ensure that the tool remains accurately centred and the bearings are pressed in straight (on the smallest drift sizes, the 8mm rod itself ensures alignment).

How To Use

The press tool is simple to use.

Here's a quick demo:

Two drifts are supplied which accurately match the size of the bearing. The shape of the drifts ensures that it accurately centres on the bearing, and that pressure is applied to the outer race.

Tightening the nuts or handles draws the drifts together, pressing the bearing into place. For best results install one bearing at a time.

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

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

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.
