Tapered Roller Bearings SKF 32020 X

The SKF 32020 X tapered roller bearing accommodates combined radial and axial loads and, with its main dimensions of 100 × 150 × 32 mm, is suitable for demanding shaft mountings.

The single-row 32020 X tapered roller bearing simultaneously withstands high radial forces and axial forces from one direction. As a complete tapered roller bearing in the SKF Explorer design, this rolling bearing features a dimensionally stable sheet steel cage that guides the truncated cone-shaped rollers evenly along the raceways. The bearing is designed for a temperature range of -30 to +120 degrees and complies with the standard tolerances of tolerance class P0/PN or ABEC 1.

What is the 32020 X tapered roller bearing suitable for in practice?

It is primarily fitted in bearing locations where high radial forces occur in combination with axial forces acting from one side, and where precise shaft guidance is required. As a single tapered roller bearing, by its very design, can only accommodate axial forces in one direction, it is fitted in combination with a second, oppositely mounted tapered roller bearing in an O or X arrangement.

What is the function of the Explorer design and the sheet steel cage?

The sheet steel cage maintains the rollers at a uniform distance and prevents direct contact between the rolling elements, which contributes to smooth running. In combination with the SKF Explorer design, the internal geometry is characterised by optimised transitions at the raceways. During assembly, the separable design facilitates the separate installation of the outer ring (cup) and the inner ring assembly (cone), allowing the desired operating clearance to be adjusted via axial preload.
