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. These bearings may be preloaded at the factory so that the correct preload will develop within the bearing. 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 load used by NTN is 30 deg, bearings made to a 40 deg contact angle carry the suffix B. For high speed grinding spindles, the 7000C, 7200C and the 7300C series are available. They are high accuracy bearings with a 15 deg contact angle, and phenolic resin cages for high speed operations.

NTN Angular Contact Ball Bearing, Round Bore Small, Series: 72B, 25 mm Bore Dia, 52 mm Outside Dia, 1 Row, 15 mm W, 40 deg Contact, Open Closure, 14800 N, High Carbon Chrome Steel Bearing, Pressed Steel Cage, 12000 rpm Grease/16000 rpm Oil Maximum, -40 to 120 deg C Angular Contact Ball Bearing. Balls and the inner ring and outer ring raceways are designed for contact in a specific contact angle, which means this type of bearing is suitable for composite loads (axial load and radial load). The contact angle means that axial force components are generated when a radial load is applied, so these are normally used in pairs at either end of a shaft.
