Angular Contact Ball B. FAG 7220 -B-MP-UO

The FAG 7220 -B-MP-UO angular contact ball bearing (100x180x34 mm) can accommodate high radial loads as well as unilateral axial loads when fitted without clearance.

The 7220 -B-MP-UO angular contact ball bearing is a single-row rolling bearing made from bearing steel (100Cr6) for demanding industrial applications. The design features a bore of 100 mm, an outer diameter of 180 mm and a width of 34 mm. Thanks to the raceways that are offset at an angle to one another, this design is particularly suitable for combined loads where, in addition to radial forces, high axial forces act simultaneously on the shaft in one direction.

What loads does the 7220 -B-MP-UO angular contact ball bearing accommodate during operation?

This bearing is primarily used where precise shaft guidance and high load-carrying capacities are required under combined loads. As a single angular contact ball bearing can only accommodate axial forces in one direction, users typically fit this type in pairs, with one bearing facing the other. The solid brass cage ensures stable guidance of the rolling elements even under dynamic operating conditions.

What does the UO designation mean in relation to paired installation?

The suffix ‘UO’ denotes a universal design for installation in pairs. When two of these bearings are assembled in an O or X configuration, the bearing assembly is immediately free of play without the need for manual fitting of shims. Together with the increased contact angle of 40 degrees (designation B), this design enables high axial rigidity. As an open component without an integrated seal, the bearing can be integrated directly into existing oil or grease lubrication circuits.
