NTN Rolamentos de esferas de contacto angular

Super Precision High Speed Angular Contact Ball Bearings are designed for rigid, high speed, high tolerance applications. Spindle bearings used in pairs arrangemet can support axial forces on both directions and moments. Bearings in a tandem arrangement can only support axial loads in one direction. Spindle bearings are available with a 15 degree or 25, 30 degreee contact angle. Various cage options are available as well as the use of ceramic balls which allow for higher speed.

Single row angular contact ball bearings feature raceways with high and low shoulders. These opposing raceways are designed to carry thrust load in one direction. NTN can preload the bearings at the factory so that the correct load will develop once the bearing is put into service. The bearings in this series are assembled with a specific internal clearance, so that they will have a specified contact angle under load. The standard contact angle used by NTN is 30° but, in many cases, a 40° contact angle can also be specified. We also offer special high-speed bearings with phenolic resin cages with a 15° contact angle.
