Angular Contact Ball B. FAG 3317 -M

The FAG 3317-M angular contact ball bearing is an open, double-row rolling bearing with a brass cage, with main dimensions of 85 x 180 x 73 mm.

As a double-row bearing, the FAG 3317-M angular contact ball bearing accommodates combined radial and axial loads in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this version has a bore of 85 mm, an outside diameter of 180 mm and a width of 73 mm. Thanks to the standard radial clearance and the open design without sealing washers, the component can be flexibly integrated into existing lubrication systems. This provides industrial users and maintenance engineers with a robust component for demanding bearing applications.

What is the 3317-M double-row angular contact ball bearing suitable for?

In terms of design, the bearing corresponds to a pair of single-row angular contact ball bearings arranged opposite each other; however, it requires less axial space. Typical applications include industrial gearboxes and general mechanical engineering, where rotating shafts subjected to high radial forces must also be supported in both axial directions. As the design is seal-less, the bearing is particularly suitable for oil- or grease-lubricated housing designs that require a continuous flow of lubricant.

What advantages does the brass cage offer in the 3317-M version?

The suffix ‘-M’ denotes the brass cage, which guides the rolling elements stably and precisely. Compared with standard sheet-steel cages, brass is characterised by high mechanical strength and favourable free-running properties. In conjunction with the specified temperature range of –20 to +150 degrees Celsius, this version is suitable for demanding thermal or dynamic operating conditions. Manufacture to tolerance class P0 (equivalent to ABEC 1) meets the standardised accuracy requirements of mechanical engineering.
