Tapered Roller Bearings SKF 32015 X

The SKF 32015 X tapered roller bearing, with dimensions of 75 × 115 × 25 mm, can accommodate high radial loads as well as unilateral axial loads.

The single-row tapered roller bearing 32015 X from SKF is designed for demanding industrial applications involving combined radial and axial forces. Thanks to its tapered rollers and raceways, this bearing distributes the forces acting upon it evenly across the contact surfaces. This complete roller bearing, with a 75 mm bore, 115 mm outer diameter and 25 mm width, belongs to the Explorer performance class. The integrated sheet steel cage guides the rolling elements with low vibration within the specified temperature range of -30 to +120 degrees.

What is the 32015 X tapered roller bearing suitable for in operation?

The 32015 X tapered roller bearing is primarily used where high radial forces are combined with axial forces acting from one side. Typical applications can be found in general mechanical engineering and gearbox construction involving directed axial loads. As single-row tapered roller bearings can only accommodate axial loads in one direction, they are often fitted in pairs in an X or O configuration. Together with the dimensionally stable sheet steel cage, the bearing remains mechanically robust at operating temperatures ranging from -30 to +120 degrees.

What is important to bear in mind regarding tolerance class P0 and installation?

This rolling bearing is manufactured to tolerance class P0 or ABEC 1, which corresponds to the standard precision for general mechanical engineering applications. The specified mounting dimensions of 75 mm shaft diameter and 115 mm housing bore require the surrounding components to be manufactured to exact tolerances. As the inner ring with roller set and the outer ring can be fitted separately, installation can be carried out in stages. The correct adjustment of the axial bearing clearance or preload against the mating bearing determines the subsequent smoothness of operation.
