Angular Contact Ball Bearings
Angular contact ball bearings have raceways in the inner and outer rings that are displaced relative to each other in the direction of the bearing axis, enabling them to carry combined radial and axial loads. The contact angle (typically 25°, 30°, or 40°) determines the axial load capacity — the higher the angle, the greater the thrust capability. SKF offers single-row, double-row, and four-point contact variants, along with matched pair sets for high-stiffness, high-precision applications. These bearings are essential in electric motors, pumps, gearboxes, machine tool spindles, and automotive applications. Single-row angular contact bearings accommodate axial loads in one direction only, so they are invariably mounted in pairs or with a second complementary bearing. SKF’s precision manufacturing and optimized raceway geometry provide exceptional running accuracy and speed performance.

Trusted by Industry Leaders
High Axial Load Capacity
Contact angles up to 40° manage heavy thrust with minimal friction.
Adjustable Clearance and Preload
Pairs can be preloaded for increased rigidity and positional accuracy.
High-Speed Performance
Single-row, standard precision bearings reach high RPMs; super-precision for spindles.
Universal Matching
Face-to-face, back-to-back, or tandem arrangements from separately manufactured bearings.
Integrated Sealing Options
Sealed angular contact bearings available, reducing contamination risk.
Double-Row and Four-Point Designs
Double-row versions carry bidirectional axial loads in one bearing; four-point contact saves space.
Single vs. Double Row Angular Contact Ball Bearings
Single-row angular contact ball bearings are used in pairs or combined with a deep groove or cylindrical roller bearing to handle axial loads in both directions and provide precise shaft guidance. Double-row bearings integrate two single rows back-to-back, providing bidirectional thrust capability in a compact package, ideal for wheel hub bearing units and pumps.
Preload and Arrangement Options for Angular Contact Bearings
Back-to-back (suffix DB) arrangements yield high rigidity and support moment loads. Face-to-face (DF) arrangements allow more misalignment tolerance. Tandem pairs (DT) double the single-direction load capacity. SKF’s matched sets (suffixes like G, GA, GB) deliver specified preload values without shimming.
