Bearings • Angular Contact Bearings
Angular contact bearings are one directional thrust ball bearings that support great thrust loads in one direction and some radial load. Its inner and outer rings have high shoulders for steep contact angles to support high thrust and axial rigidity. They are offered as duplex ball bearings and double row, angular contact ball bearings. Duplex ball bearings support thrust loads in two directions and can be used in tandem for thrust loads in one direction. Double row, angular contact ball bearings are two single angular contact ball bearings. Their thrust capacity is limited in one direction.

SKF's angular contact ball bearings have raceways in the outer and inner rings that are displaced in the direction of the bearing axis respectively. These products are designed to accommodate simultaneously acting radial and axial loads. Models include four-point contact, single row and double row designs.
National manufactures customized, light duty, angular contact bearings varying in diameter and width, shape, type of material, ball compliment, lubrication, shields and surface finishing. Types include multi-function, stamped outer race and plastic angular contact bearing designs. Custom designs to fit any shape and carry any load requirement are available.
ARB provides angular contact bearings with expected load contact angles of 15, 25, 30 or 40 degrees, radial components (none, light or high), axial components (none, light or high), and preload N of 0, 220 (50lbs), 440 (100lbs), and 880 (200lbs). Products can be sold as single units, individually boxed, and interchangeable in pairs.
Messinger (a Kingsbury brand) angular contact ball bearings are designed with offset raceways between the inner and outer rings which create a specific contact angle under load. These products can carry combined axial and radial loading, can be used for high speed applications, and can be produced to an ABEC 5 precision class.
