Thin Section Ball Bearings - 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.
Duplex bearings are a pair of angular contact RBC Thin Section Ball Bearings specially ground for use as a matched set. A duplexed pair can be used to provide accurate shaft location, to increase capacity or to increase stiffness of the bearing assembly. A duplex pair of RBC Thin Section Ball Bearings is ground so that when mounted using recommended fits, there will be no internal clearance in the bearings. There are three basic mounting methods to accommodate different loading requirements:
• Back-to-Back (DB), B-Type
• Face-to-Face (DF), F-Type
• Tandem (DT), T-Type
Features of A-Type Thin Section Bearings:
• Large Diameter
• Light Weight
• Small Cross Section
• Circular Pocket Ball Separator
