Thin Section Bearings

Inch Open Type A Thin Section 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 contact Silverthin™ for application of these bearings.
