Pressed Steel Cages Single-Row Angular Contact Ball Bearings

Contact Now

As previously mentioned, angular contact bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. This can bee done by matching up multiple single row bearings or by utilizing double row angular contact bearings which may offer some econmic benefits.  However, utilizing multiple single sow angular contact ball bearings can offer greater design flexibility and performance in many cases.

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.
