Tapered Roller Bearings SKF 320/22 X

The SKF 320/22 X tapered roller bearing can withstand high radial and single-direction axial loads whilst maintaining compact dimensions of 22 × 44 × 15 mm.

The SKF 320/22 X tapered roller bearing is a single-row rolling bearing in the Explorer series. With a bore of 22 mm, an outer diameter of 44 mm and a width of 15 mm, this bearing is suitable for industrial applications involving combined loads. The truncated conical rollers run on inclined raceways, enabling the bearing to support radial forces and single-direction axial forces. The bearing is supplied as a complete unit, comprising an inner ring with a set of rollers and the corresponding outer ring.

How does the 320/22 X tapered roller bearing accommodate combined loads?

Tapered roller bearings of this design are used wherever radial and axial forces act on the shaft simultaneously. As single-row tapered roller bearings, by their very design, can only accommodate axial forces in one direction, they are usually fitted in pairs with a mirror-image mating bearing. This arrangement ensures play-free and rigid guidance of rotating components. Manufactured to tolerance class P0 or ABEC 1, the bearing complies with standardised specifications for dimensional and concentricity accuracy.

What are the distinctive features of the sheet steel cage and the Explorer version?

The integrated sheet steel cage maintains the tapered rollers at a uniform distance and distributes the forces acting on them during operation. The design withstands thermal influences within a temperature range of -30 to +120 degrees. The SKF Explorer designation indicates an optimised internal geometry designed to support the formation of a lubricating film on the contact surfaces. During installation, the bearing clearance must be precisely adjusted in relation to the second tapered roller bearing.
