Tapered Roller Bearings FAG 31313

The FAG 31313 tapered roller bearing, measuring 65 × 140 × 36 mm, accommodates high radial and axial forces simultaneously in industrial assemblies.

The FAG 31313 tapered roller bearing is designed as a single-row rolling bearing for combined loads. Owing to the tapered shape of the rolling elements, this component transmits radial forces together with axial forces from a single direction. The complete bearing has a 65 mm bore, an outer diameter of 140 mm and a width of 36 mm. A sheet steel cage guides the set of rollers along the inner ring raceway.

What is the 31313 tapered roller bearing suitable for?

This bearing is primarily used in general mechanical engineering and for shaft support applications where single-sided axial forces act on a rotating shaft. As a single-row tapered roller bearing supports axial loads in only one direction, designers usually position the component in a mirror-image configuration opposite a second bearing. The geometry ensures line contact, which enables high rigidity and load-carrying capacity under mixed loads.

What role do the sheet steel cage and tolerance class P0 play?

The fitted sheet steel cage keeps the tapered rollers spaced apart and withstands operating temperatures ranging from –30 to +120 degrees. With the standard tolerance P0 or ABEC 1, the component meets the broad requirements of standard industrial applications without requiring special fits. As the inner ring, including the roller cage, and the outer ring can be fitted separately, the bearing clearance can be precisely adjusted during installation via axial alignment.
