Axial Angular Contact Ball Bearings for Bicycles — headset bearing

The ACB headset bearings are high quality angular contact ball bearings. They support the fork steerer tube in the bicycle frame at the top and bottom of the head tube and together form the headset. The use of headset bearings is a basic requirement for steering a bicycle, as they allow the fork to rotate. Headset bearings absorb enormous radial and axial forces during steering. As a result, the lower headset bearing at the fork crown needs to be replaced relatively often. The dimensions of the headset bearing are based on the inner diameter of the head tube and the outer diameter of the steerer tube and can be measured on the bearing that is to be replaced.

Versions of axial angular contact ball bearings

Single row
Usable in case of high radial and axial loads in both directions.

Material description of axial angular contact ball bearings

Angular contact ball bearings made of rolling bearing steel
are cost-effective, withstand very high load capacities. The cage material is PA66 nylon and therefore longer lasting.
