Tapered Roller Bearings FAG 33211

The single-row FAG tapered roller bearing 33211, with main dimensions of 55 × 100 × 35 mm, accommodates high radial loads as well as axial loads on one side in mechanical engineering applications.

The FAG 33211 tapered roller bearing is an open, single-row roller bearing in a standard design. Thanks to the angled, tapered rolling elements, this design effectively transfers combined forces to the raceways. The robust sheet steel cage guides the set of rollers evenly and withstands mechanical stresses during continuous operation. With a permissible temperature range of –30 to +120 degrees, the component is suitable for a wide range of industrial drive systems.

In which installation scenarios does the 33211 tapered roller bearing prove its worth?

Typical applications can be found wherever guided axial forces in one direction occur alongside radial forces. Designers primarily integrate this bearing into industrial gearbox designs as well as in rigid shaft mountings with combined force components. As single-row tapered roller bearings can only accommodate axial loads from one direction, in practice they are usually fitted in pairs in an X or O arrangement, mirroring a second tapered roller bearing, in order to accommodate axial forces from both sides.

What properties do the sheet steel cage and the P0 tolerance offer?

Manufacture to standard tolerance P0 (corresponding to PN and ABEC 1) defines a standardised dimensional accuracy for standard bearing seats. The inner ring, including the roller ring, and the outer ring can be fitted separately, which simplifies handling during installation and maintenance. The dimensionally stable sheet steel cage ensures uniform roller guidance with low frictional resistance. Fitters adjust the required operating clearance during installation by carefully positioning the bearing against the mating bearing as required.
