NSK Super Precise Ball Bearings

Detailed Product Description

  Angular contact ball bearings are designed for combination radial and axial loading. Single-row bearings have high thrust capacity in one direction. Some single-row bearings are specifically designed for duplex mounting in sets for maximum performance. Double-row Conrad bearings can accommodate thrust in both directions.
Size Range:

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

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

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.
Applications
