Identification of bearings

If you replace the bearings yourself, you can find the right bearing under ”bearing identification” and buy just the bearings. The exploded views give you the part numbers of the individual parts.

The scatterplots on this site are helpful when you are looking for bearings for Bosch, Brose, Mahlen, Panasonic, Shimano or Yamaha engines.

The most common cause of bearing failure is wear or water getting into the bearings. We also supply O-rings, seals and circlips.Contact us if you cannot find a suitable product for your needs on our website, we are happy to help!
