Tapered Roller Bearings FAG 32028 -X-XL-P5

The FAG tapered roller bearing 32028 -X-XL-P5 (140x210x45 mm) offers enhanced precision in accordance with tolerance class P5 for demanding industrial applications involving combined radial and axial loads.

The 32028 -X-XL-P5 tapered roller bearing is a single-row rolling bearing in metric dimensions, comprising an inner ring, a flangeless outer ring and a guided set of rollers. The geometry of the tapered rollers enables the simultaneous absorption of high radial forces and single-sided axial forces. As it is manufactured to tolerance class P5 (equivalent to ABEC 5), this roller bearing exhibits reduced running and dimensional deviations compared to standard tolerance. A robust sheet steel cage guides the rolling elements evenly along the raceways.

What is the 32028 -X-XL-P5 tapered roller bearing suitable for?

The 32028 -X-XL-P5 tapered roller bearing is primarily used in gearboxes, spindle bearings and drive shafts where precise shaft guidance and high concentricity are required. As single-row tapered roller bearings, by their design, can only accommodate axial forces in one direction, they are usually fitted in a mirror-image configuration as a pair of bearings in an O or X arrangement. The bearing is designed for a temperature range of -30 to +120 degrees and is therefore suitable for industrial applications subject to thermal stress.

What advantages does tolerance class P5 offer with this rolling bearing?

Classification as tolerance class P5 (ABEC 5) means tighter tolerance ranges for the bore, outer diameter and radial runout compared with the standard tolerance. This reduces vibrations at higher speeds and results in a more even load distribution across the individual tapered rollers. During assembly, the fact that the bearing can be dismantled facilitates the separate alignment of the inner and outer rings. The correct adjustment of the axial bearing clearance or preload during installation affects the operating temperature and service life.
