Angular Contact Ball B. FAG 7222 -B-MP

The contact angle describes the inclination of the line connecting the points of contact between the balls and the raceways relative to the radial plane. At an angle of 40 degrees, the component can withstand particularly high axial forces in one direction. To support forces acting in the opposite direction, users usually combine this single-row bearing with a mating bearing mounted in the opposite direction.

The abbreviation MP indicates a brass cage. This cage material is characterised by high resistance to vibrations and thermal stresses. It guides the rolling elements stably within the raceway and broadens the range of possible applications in industrial settings subject to higher mechanical stresses compared with standard sheet metal cages.

The bearing, made from standard roller bearing steel 100Cr6, is designed for operating temperatures ranging from -20 to +150 degrees. Within this temperature range, the dimensional stability of both the steel and the brass cage is maintained. When commissioning the bearing, ensure that the selected lubricant is also suitable for the intended temperature range.

As this bearing is designed without integrated sealing washers, the lubricant reaches the raceways and balls directly. Depending on the system design, you can lubricate the bearing via an external oil lubrication system or by applying grease to specific areas. At the same time, the surrounding housing design must prevent the ingress of dirt and the loss of lubricant.

This product has the standard radial bearing clearance. However, in the case of single-row angular contact ball bearings, the actual operating clearance is only established during installation by means of precise alignment against a second bearing. The fits on the shaft and housing, as well as thermal expansion, have a significant influence on the remaining clearance during operation.
