Inch Size Chart of Thin Section Four-point Contact Ball Bearing
The difference between X-type four-point angular contact ball bearings and A/C-type bearings lies in the shape of their ball grooves. The deep groove depth and four-point contact structure enable the bearing to withstand radial and axial loads as well as torque loads, similar to the back-to-back combination of a pair of A-type bearings.
