Tech Brief – Bearing seal cross-section At FUSHI we manufacture and use Angular Contact Bearings (ACB) for our headsets. We use only the best manufacturing and quality control methods available.The manufacturing process begins with the rough shape of the bearing races being machined from high quality steel. Both the inside and outside of each race is then precision stone-ground to reach its final shape.Computer controlled grinding equipment is used to grind each race to exact tolerances.The races are then assembled with the balls to create the finished bearing.

The second category of bearings is the roller bearings which include the standard roller bearing and the tapered roller bearing. Both of these use cylindrical rollers.2. There are many different types of bearings. Which one is best for the bicycle headset and why?Answer: Angular contact bearings are the most appropriate bearing for most headset applications. The primary reason is due to the fact that it is very efficient at dealing with the angular force that is exerted upon it. Whereas most deep groove industria
