Tapered Roller Bearings SKF 32220

The SKF 32220 tapered roller bearing, with a 100 mm bore, 180 mm outer diameter and 49 mm width, offers a high load-carrying capacity for combined loads.

The 32220 tapered roller bearing is a single-row rolling bearing for industrial applications involving combined radial and axial loads. The line contact between the tapered rollers and the raceways of the inner and outer rings ensures that the design retains its dimensional stability under load. Manufactured as a complete bearing in the SKF Explorer design, this unit features a sheet steel cage. The component is suitable for operating temperatures ranging from –30 to +120 degrees and complies with the standard tolerance class P0/PN or ABEC 1.

What is the 32220 tapered roller bearing suitable for?

This tapered roller bearing is used in bearing arrangements where high combined loads act on shafts with a diameter of 100 mm. Typical applications include gearbox construction and mechanical industrial drives. As single-row tapered roller bearings are designed to accommodate axial forces in one direction only, they are usually fitted in pairs in a mirror-image configuration. This arrangement against a second bearing provides axial guidance on both sides and allows the bearing clearance to be adjusted.

What are the distinctive features of the 32220 tapered roller bearing in the Explorer design?

The Explorer version from SKF features machined surfaces and optimised contact geometries between the roller end faces and the guide flange. This promotes the formation of a lubricating film and reduces friction losses. As a separable bearing, the outer ring can be fitted separately from the inner ring assembly, which simplifies installation. The sheet steel cage guides the rolling elements within a temperature range of -30 to +120 degrees. External seals and lubrication must be provided during installation.
