Size Range

Single-row: 10 mm - 150 mm (0.3937 in. - 5.9055 in.) boreDouble-row: 12 mm - 150 mm (0.4724 in. - 5.9055 in.) bore

Design Attributes

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.

NSK offers one of the most comprehensive ranges of Angular Contact Ball Bearings which have been designed to meet  original equipment manufacturers' demanding requirements. These bearings have a contact angle which enables them

to withstand  significant axial load sin one direction together with radial loads. They are generally used in pairs, triplex sets, 

quadruplex sets, or multiplex sets since an axial component is generated when a radial load is applied.

Consist:Angular contact ball bearings have raceways in the inner and outer rings that are displaced with respect to each other in the direction of the bearing axis. This means that they are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads

Characteristic of Angular Contact Ball Bearings

The axial load carrying capacity of angular contact ball bearings increases with increasing contact angle. The contact angle α is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the load is transmitted from one raceway to another, and a line perpendicular to the bearing axis .
