NTN 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  bearings can accommodate thrust in both directions.Angular Contact. NTN 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.

Paired mounting of two or more single row angular contact ball bearings is commonly used to accommodate heavier or two-directional thrust loads and/or radial loads in various combinations. Tandem mounting is used for heavy unidirectional thrust loads and duplex mounting (either face-to-face or back-to-back) for two-directional thrust loading.
