With their unique design, [angular contact bearings]  minimize wear and friction and are suitable for combined loads as they absorb force in both radial and axial directions. We offer angular contact bearings in single row and double row configurations.

With our extensive inventory, we can ship angular contact bearings within a week – much faster than manufacturers themselves. We also offer inventory management services and JIT capabilities that ensure you always have the right supply of angular contact bearings when you need them.Like our clients, our commitment to quality is very important to us. We are ISO 9001:2008 certified, maintain lot traceability for all angular contact bearings, and our quality control efforts are continually being evaluated and improved.

Designed for high accuracy and excellent high-speed performance. Angular contact ball bearings are designed to carry combined loads: both axial and radial.Angular contact ball bearings are suitable for applications which require high accuracy and good high-speed performance. This type of bearing is designed to carry a combined load.

Angular contact bearings are designed such that a contact angle between the races and the balls is formed when the bearing is in use. The major design characteristic of this type of bearing is that one, or both of the ring races have one shoulder relieved, or higher than the other. In order for these bearings to function properly, they must be assembled with a thrust load. This loading (or preload) creates a line of contact (or contact angle) between the inner race, the ball and the outer race. The preload can be built into the koyo bearing or created when the bearing is inserted into an assembly. The contact angle varies from 15° to 40° and is measured relative to a line running perpendicular to the bearing axis. Angular contact bearings are unidirectional thrust bearings that can withstand heavy thrust loads and moderate radial loads.

Important dimensions to consider when searching for angular contact bearings include design units bore, outside diameters, and outer ring width.  Design units can be in either inches or metric units.  Some manufacturers may specify parts in both.  The bearing industry uses a standard number system for bearings with metric diameter bores.  For bore sizes 04 and up multiply by 5 to obtain the bore in millimeters. 

Important operating specifications to consider when searching for angular contact bearings include rated speed, static radial load, and dynamic radial load.  The rated speed of a fag bearing running with grease lubrication is lower than that of a bearing with oil lubrication.  The static radial load is the maximum radial load a bearing can endure without excessive permanent deformation.  The dynamic radial load is the calculated constant radial load, which a group of identical bearings with stationary outer rings can theoretically endure for a rating life of 1 million revolutions of the inner ring.

Manufacturers typically assign an ABEC rating to bearings.  ABEC (Annular Bearing Engineers' Committee) ratings classify different accuracy and tolerance ranges for bearings. The higher the ABEC number the tighter the bearing tolerances.  Please consult the tables in the search form for Angular Contact Bearings for tolerances and other rating equivalents.
