The 7221BECBP SKF is a single row angular contact bearing. These bearings have solid inner- and outer rings. They owe their name to the contact angle that is created as the raceways of the inner and outer rings are offset from each other along the bearing axis. The bearing rings have one high and one low shoulder. Thanks to the low shoulder, a large number of balls can be incorporated in the bearing. Single row angular contact bearings can support high radial forces and axial forces in one direction. The greater the contact angle, the greater the axial load capacity of the bearing.
The 7221BECBP SKF is suitable for universal matching. Bearings for universal matching can be assembled directly beside each other various arrangements. No shims or other spacers are required to obtain the predetermined clearance or preload and/or even load distribution. Paired mounting is used if the load carrying capacity of a single bearing is insufficient, or if there are combined or axial loads in both directions. When using a CB bearing set in X or O arrangement, the axial clearance in unassembled condition is Normal (standard).
