Angular Contact Ball B. FAG 7230 -B-MP-UA

The FAG 7230 -B-MP-UA angular contact ball bearing, with dimensions of 150 × 270 × 45 mm and a contact angle of 40 degrees, is specifically designed to accommodate combined loads.

This single-row angular contact ball bearing 7230 -B-MP-UA transmits radial forces as well as unidirectional axial forces via angularly offset raceways. The manufacturer, FAG, produces this open bearing from standard rolling-element bearing steel (100Cr6) with standard radial clearance. Thanks to its solid brass cage, the rolling element guidance withstands high thermal stresses in the temperature range from –20 to +200 degrees. It is manufactured to tolerance class P0/PN or ABEC 1 with a cylindrical bore.

What is the 7230 -B-MP-UA angular contact ball bearing suitable for in practice?

Designs subject to simultaneous radial and axial forces require components with a steep contact angle. With its contact angle of 40 degrees, this rolling bearing absorbs high axial forces in one direction. Typical applications are found primarily in shaft mountings subject to high combined loads. As a single bearing only supports axial loads on one side, a mating bearing on the opposite side of the shaft is usually required, or it must be installed as a matched bearing set.

What does the suffix ‘UA’ mean in relation to pairing?

The designation ‘UA’ identifies this product as a universal bearing for installation in pairs. If you fit two bearings of this type directly next to each other in an O or X arrangement, a small amount of axial clearance is achieved without the need for shims. The suffix ‘B’ stands for the 40-degree contact angle, whilst ‘MP’ denotes the robust brass cage. As the bearing is of an open design, you must incorporate external sealing and lubrication into the housing design.
