Tapered Roller Bearings SKF 32021 X

Thanks to the inclined roller tracks, the design simultaneously absorbs high radial and axial forces in one direction. To accommodate axial loads on both sides, a second tapered roller bearing in an O or X arrangement is always required as a counter bearing. This also allows the desired operating clearance in the system to be precisely adjusted.

The Explorer classification denotes bearings with optimised raceway geometry and improved surface finish on the rolling elements. These design refinements promote the formation of a lubricating film in the contact area between the roller and the raceway. In continuous industrial use, this results in greater operational reliability and reduced friction under demanding load conditions.

The approved operating temperature range is from -30 to +120 degrees. This range is determined by the metallurgical dimensional stability of the components and the sheet steel cage used in the construction. When commissioning the unit, please ensure that the lubricant used is also suitable for this temperature range.

The inner ring, together with the roller cage, and the outer ring can be fitted separately. This allows both components to be press-fitted onto the shaft or fitted into the housing independently of one another. This prevents forces being transmitted directly via the rolling elements during the assembly process and facilitates future maintenance work.

According to international standards, P0 denotes the standard tolerance class for metric rolling bearings and corresponds to the ABEC 1 classification. It specifies the permissible dimensional and concentricity deviations for diameters and widths. This accuracy grade covers the vast majority of industrial requirements in mechanical engineering.
