Tapered Roller Bearings SKF 33215

The SKF 33215 tapered roller bearing accommodates high radial and axial loads simultaneously, whilst maintaining compact dimensions of 75 × 130 × 41 mm.

This single-row SKF 33215 tapered roller bearing belongs to the radial roller bearing group and is designed as a complete rolling bearing. Thanks to the line contact between the tapered rollers and the raceways, the component transmits high loads whilst maintaining high rigidity. The SKF Explorer design features optimised internal geometry and precision-finished surfaces on the rollers and raceways. The component is designed for a temperature range of -30 to +120 degrees.

In which applications is the 33215 tapered roller bearing used?

The bearing is used where bearing arrangements must withstand combined loads consisting of radial forces and unidirectional axial forces. Typical applications can be found in general mechanical engineering, as well as in gearbox stages and industrial shafts. As single-row tapered roller bearings, by their design, can only accommodate axial forces in one direction, in practice they are usually fitted in pairs in an O or X arrangement with a second bearing mounted in the opposite direction.

What advantages does the Explorer version with a sheet steel cage offer?

The integrated sheet steel cage precisely maintains the spacing between the rolling elements and withstands mechanical stresses during day-to-day operation. At the same time, manufacture to standard tolerances (tolerance class P0/PN or ABEC 1) ensures a dimensionally accurate fit on the 75 mm shaft and in the 130 mm housing. One advantage of this design is its disassemblability: the inner ring with roller set and the outer ring can be fitted separately, which facilitates maintenance work and bearing adjustment on machinery.
