Thin Section Selection Guide

Type AAngular Contact Bearings

In applications with axial loads in one direction 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. Different configurations for duplex bearings are shown in the Engineering section of this catalog.

Please consult SilverThin engineering for application of these bearings.

Type CRadial Contact 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.

Please contact Silverthin for radial bearing use with combined radial loads with axial or moment loading and for limiting speeds and separator selection.

Type X4-Point Contact 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.

When specifying this type of bearing for use with axial or moment loads combined with radial loads application speed (rpm) is a real concern. Please contact SilverThin engineering for information on combined load and limiting speeds.
