7203-B-MP-UA FAG Angular Contact Bearing 17x40x12mm

FAG Single row angular contact ball bearings are particularly suitable where:
Bearing arrangements must support combined loads, i.e. radial and axial loads acting simultaneously
Moderate to high loads are present on one side
Rigid axial guidance is required
The bearing arrangement must be axially clearance-free or preloaded
High speeds are required under higher radial and axial loads
The bearing arrangement is to run quietly in addition to meeting the requirements stated above

FAG Single row angular contact ball bearings are part of the group of radial ball bearings. The self-retaining units have solid outer and inner rings. The rolling elements are guided by cages made from polyamide, sheet steel, or brass. The bearing rings are designed with one high shoulder and one low shoulder. As a result of the different shoulder heights, the mounting method differs from that of deep groove ball bearings. The possible number of balls for angular contact ball bearings with identical dimensions is higher than for deep groove ball bearings. In contrast to deep groove ball bearings, the raceways on the inner and outer rings are arranged obliquely to each other in the direction of the bearing axis. As a result, the forces are transmitted from one raceway to the other at a defined contact angle (oblique to the radial plane)

For bearing positions with only one bearing each
These angular contact ball bearings can be considered when only one bearing is used per bearing position. As the bearings have standard bearing ring tolerances (they are manufactured to tolerance class Normal), they are not suitable for mounting directly adjacent to each other. In such cases, universal bearings should be used.
