Feature●Tech Brief ? Bearing seal cross-section●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 color of the seal is not sure. If you mind it, please contact us before you buy the bearing.Description
