AITA hybrid ceramic bearings are designed to perform and made to last. It only consumes 20% of the power compared with the steel bearing.
As one of the Australian owned ceramic bearing brands, we design the bearings for sports and check each bearing by hand before shipping it to you.

It is always not easy to find the right bearings to match your current ones but with AITA, we provide the bearing code, which normally can be found on your current bearing rubber seals such as 6803-RS(61803-RS); RS stands for rubber seal. 

The bearing's actual size is measured as Inner Diameter (ID) x Outer Diameter (OD) x Width (W) in mm.

For instance, a 6803(61803) bearing size is ID 17mm x OD 26mm x W 5mm

All AITA ceramic bearing comes with a 2-year warranty.

    Worth the investment

    Posted by Peter on 12th Sep 2020

    I recently bought some of your ceramic bearings for my Edmonda and they’ve been well worth the investment. Now I am looking for a SHIMANO SMBB7141B compatible for Dura Ace 9100 24mm crank, if you can advise. Thank you.
