Specific geometry of angular contact bearing raceways and shoulders creates ball contact angles that support higher axial loads.
Expanded options include special lubricants, cage materials, preloads and coatings for additional corrosion resistance.
Angular contact ball bearings are engineered for use in high-speed, high precision applications for:
