Tapered Roller Bearings SKF 32313

The SKF 32313 tapered roller bearing, with dimensions of 65 × 140 × 51 mm, is designed to withstand high radial loads as well as axial loads on one side in mechanical engineering applications.

The single-row tapered roller bearing 32313 is designed as a complete rolling bearing and consists of an inner ring with a set of rollers and the matching outer ring. With a bore of 65 mm, an outside diameter of 140 mm and a width of 51 mm, this design is one of the heavily dimensioned bearings for heavy-duty industrial applications. As an SKF Explorer variant, the bearing features a specially optimised internal geometry for even load distribution.

What loads and mounting configurations can the 32313 tapered roller bearing accommodate?

The 32313 tapered roller bearing is primarily used where high radial forces and single-sided axial forces occur simultaneously. Typical applications include gearbox construction, industrial drives and supported shaft systems. As single-row tapered roller bearings can only support axial forces in one direction, designers usually fit them in pairs in a mirror-image arrangement. Thanks to their separable design, the inner and outer rings can be installed separately.

What is the function of the cage and the tolerance class in this bearing?

A dimensionally stable sheet steel cage guides the rolling elements precisely and maintains a defined spacing between them, even at varying speeds. The bearing is designed for operating temperatures ranging from –30 to +120 degrees. With the standard tolerance in accordance with tolerance class P0/PN or ABEC 1, the component meets the standard requirements of general mechanical engineering for dimensional and concentricity accuracy, which makes replacement during maintenance work predictable and reproducible regardless of the manufacturer.
