MTB Frame Bearing Press ***Please read the entire description to ensure this tool is suitable for your needs***
This tool is manually machined in house at our workshop in Lancashire. It is the same MTB Frame Bearing Press we have been using since 2016 for the vast majority of the frame bearing swaps we do on behalf of customers.
We decided to make our own bearing press as there aren’t many cost effective (certainly for the home user anyway) tools available on the market.
What is included with your MTB Frame Bearing Press?
With each kit we include:
- 10 x 6082 Aluminium spacers in 41, 36, 31, 29, 27, 25, 23, 21, 20 and 18mm – the most common bearing OD’s you will encounter in frame bearing kits.
- 2 x lengths of mild steel leadscrew, the majority of the time you will use the short one.
- 2 x 14mm brass nuts.
- 2 x washers.
What can and what can’t this MTB Frame Bearing Press be used for?
It can be used for:
- Pressing frame bearings into linkages, swingarms and mainframes where there is a flat area on each side of the bearing corresponding in diameter with the above listed dimensions. You need a flat area to ensure that the lead screw remains at 90 degrees to the frame and the bearing is pressed in straight. If the lead screw is not straight you may damage your frame and or the tool.
It can’t be used for:
- Frame bearing extraction, you need a blind bearing puller.
- Frame bearings which have an extended inner race e.g. Mk1 YT Capra stays, most Whyte Bikes. If you use it for bearings of this type you will probably damage the bearing.
Why we chose the materials we did.
We have been using the same kit made from the same materials for the last few years now in our workshop with no failures. The reason we decided to use Brass and mild steel was as a safety net against user error. If used correctly frame bearings go in nice and easy with the minimum of fuss.
If you do send the bearing it at an angle and apply too much force eventually the threads on the nut will strip and or the bar will bend, hopefully before you damage the frame.
You can use any standard M8 threaded bar and nuts if you are feeling brave but it won’t feel as nice as the lead screw and you won’t have that safety net.
Spare brass nuts and bar can always be purchased if you get things wrong.
