Tapered Roller Bearings FAG 32311

The FAG 32311 tapered roller bearing, with dimensions of 55 × 120 × 45.5 mm, is designed to withstand high combined radial and axial loads in mechanical engineering applications.

The FAG 32311 tapered roller bearing is a single-row rolling bearing designed for industrial applications involving combined loads. Thanks to the tapered arrangement of the rolling elements, this bearing can simultaneously withstand high radial forces as well as unidirectional axial forces. With key dimensions of a 55 mm bore, 120 mm outer diameter and 45.5 mm width, the standard version is suitable for fixed mounting arrangements in gearboxes and general mechanical engineering. Maintenance engineers and designers alike appreciate the dimensionally accurate manufacture, which allows for direct replacement during repairs or in new designs.

In which applications is the 32311 tapered roller bearing used?

The 32311 tapered roller bearing is used where heavy radial loads occur alongside defined axial forces. Typical applications include gearbox designs and shaft bearings in general mechanical engineering. As single-row tapered roller bearings, by their design, can only support axial forces in one direction, they are usually fitted in pairs in an X or O arrangement, mirroring a mating bearing. This arrangement allows for precise adjustment of the operating clearance and ensures rigid guidance of the shaft under varying load conditions.

What are the characteristics of the cage and tolerance class P0?

FAG equips this complete tapered roller bearing with a sheet steel cage, which guides the tapered rollers even under high acceleration. The design complies with standard tolerance P0 or ABEC 1 and thus meets the usual precision requirements of mechanical engineering. The permissible temperature range extends from –30 to +120 degrees Celsius. The separable design also allows for the separate assembly of the inner ring with the roller set and the outer ring, which simplifies installation in confined spaces.
