Tapered Roller Bearings SKF 33022

The SKF 33022 single-row tapered roller bearing, measuring 110 × 170 × 47 mm, can accommodate high radial and axial loads simultaneously.

The 33022 tapered roller bearing is an open, single-row roller bearing in metric design. Manufactured in the Explorer version by SKF Rolling Bearings, the bearing geometry is characterised by precisely matched contact surfaces between the tapered rollers and the inner ring flange. The product supplied is a complete tapered roller bearing, comprising the inner ring with roller set and the separate outer ring. A dimensionally stable sheet steel cage guides the rolling elements evenly along the raceway and prevents the rollers from coming into contact with one another during rotational movement.

What loads can the 33022 tapered roller bearing withstand?

The single-row bearing accommodates high radial forces in combination with axial forces acting from one side. Due to the tapered arrangement of the rolling elements, some of the applied radial forces are converted into internal axial forces. In mechanical designs, a second tapered roller bearing is therefore usually fitted in a mirror-image configuration to accommodate axial forces from both directions. This paired bearing arrangement allows for the precise adjustment of operating clearance or preload to ensure a dimensionally stable shaft guidance.

What is important when it comes to tolerance class and cage design?

Manufacturing is carried out to the standard tolerance P0/PN or ABEC 1, meaning the bearing meets the standard requirements for dimensional and concentricity accuracy. The integrated sheet steel cage is designed for operating temperatures ranging from –30 to +120 degrees. As the inner ring, including the roller set, and the outer ring can be separated, both components can be fitted to the shaft and into the housing independently of one another. This simplifies the assembly process as well as subsequent testing and maintenance work.
