Tapered Roller Bearings SKF 33211

The SKF 33211 tapered roller bearing, measuring 55 × 100 × 35 mm, is a single-row roller bearing designed to withstand high combined radial and axial loads.

The 33211 tapered roller bearing is a single-row roller bearing from SKF in a tried-and-tested standard design. It has a bore of 55 mm, an outer diameter of 100 mm and a width of 35 mm. Designed in the Explorer performance class, the bearing simultaneously absorbs axial and radial forces. As the inner ring, including the roller set, can be separated from the outer ring, you can mount the components separately into the housing and onto the shaft, saving time.

What is the 33211 tapered roller bearing suitable for?

This tapered roller bearing is suitable for bearing arrangements where unilateral axial forces occur alongside high radial forces. As single-row tapered roller bearings can only accommodate axial loads in one direction, they are usually fitted in a mirrored pair with a second bearing. Manufactured to tolerance class P0/PN or ABEC 1, they ensure dimensionally stable guidance in continuous industrial use. Design engineers use this design as a standardised component for shaft bearings with combined load directions.

What are the advantages of the sheet steel cage and the Explorer design?

The integrated sheet steel cage guides the tapered rollers with low vibration and withstands mechanical stresses. In conjunction with the specified temperature range of –30 to +120 degrees Celsius, the bearing is suitable for thermally demanding operating environments in mechanical engineering. As an Explorer variant, the rolling bearing features optimised transition radii and raceway profiles, which reduce friction. When installing, ensure that the bearing clearance is correctly adjusted relative to the mating bearing to support even load distribution across the entire row of rollers.
