Angular Contact A-Type
Thin Section Ball Bearings
In applications with high axial loads the A-Type, angular contact ball bearing should be used. This bearing also works well in radial or combined radial-thrust applications. The A-Type bearing should never be used alone to support moment loads or reversing axial loading.
Two A-Type bearings are often used as a duplex pair. The three different configurations for duplex bearings are discussed in the Engineering Data section.
Radial Contact C-Type
Thin Section Ball Bearings
The C-Type, radial contact ball bearing is designed with deep ball grooves to withstand high loads. Although this bearing is used primarily in applications with radial loads, it can withstand moderate axial loads, reversing axial loads, and moment loads.
4-Point Contact X-Type
Thin Section Ball Bearings
The X-Type, or 4-point contact, ball bearing is ideal for moment loading. X-Type bearings are designed with gothic arch raceways creating 4 contact points between the balls and the raceways. This design is excellent for moment loading and reversing axial loading. The X-Type bearing can be used for other light loading conditions, but is not recommended in place of the C- or A-Type bearing for pure radial loads.
