Angular Contact Ball B. FAG 7220 -B-XL-TVP

The FAG 7220 -B-XL-TVP angular contact ball bearing, with dimensions of 100 × 180 × 34 mm, accommodates radial forces as well as single-sided axial loads.

The 7220 -B-XL-TVP angular contact ball bearing is an open, single-row radial rolling bearing made from standard bearing steel (100Cr6) with a standard radial clearance. The bearing is manufactured by FAG Wälzlager and has the standardised tolerance class P0/PN or ABEC 1. A characteristic feature of this design is the diagonally opposed raceways in the inner and outer rings. Designs with rotating shafts are provided with defined guidance, provided that the forces acting on them are predominantly in a specific axial direction.

In which installation scenarios is the 7220 -B-XL-TVP angular contact ball bearing used?

This single-row bearing is used when radial forces and unidirectional axial forces act jointly on a shaft. Due to its open design without sealing rings, the component is suitable for lubricated systems in which a lubricant circulation system or oil bath supplies the bearing. As a single angular contact bearing can only accommodate axial loads in one direction, designers usually fit a second counter-bearing on the shaft to ensure axial support in the opposite direction.

What is the function of the 40-degree contact angle and the TVP cage?

The suffix ‘B’ denotes a contact angle of 40 degrees. This angle enables the component to transfer axial forces from one raceway to the other. The designation TVP stands for a polyamide cage, which guides the rolling elements and helps to dampen running noise during operation. When designing the bearing, the permissible temperature range of -20 to +120 degrees must be taken into account, as dictated by the cage material and the rolling bearing steel.
