Product Description

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.
