Angular Contact Ball B. FAG 7234 -B-MP-UO

The FAG 7234 -B-MP-UO angular contact ball bearing, with a 170 mm bore, brass cage and a 40-degree contact angle, provides precise guidance under combined loads.

The 7234 -B-MP-UO angular contact ball bearing is a single-row rolling bearing designed for demanding industrial applications. With an internal diameter of 170 mm, an external diameter of 310 mm and a width of 52 mm, this unit can accommodate high radial loads as well as unilateral axial loads. FAG manufactures the bearing from standard rolling-element bearing steel 100Cr6 in tolerance class P0 (ABEC 1). Thanks to its open design, the bearing is suitable for use in lubricated housings, with a permissible temperature range of -20 to +200 degrees.

What is the 7234 -B-MP-UO angular contact ball bearing suitable for?

Design engineers and maintenance technicians use this design primarily in bearing arrangements subject to combined radial and axial loads. Thanks to its contact angle of 40 degrees, the bearing effectively supports axial forces in one direction. Typical applications include industrial bearing arrangements subject to high axial loads. When mounted in pairs in an O or X configuration, the bearing pair is play-free, which contributes to rigid and precise shaft guidance.

What are the advantages of the brass cage in the 7234 -B-MP-UO bearing?

The solid brass cage is characterised by high strength and favourable sliding properties. It guides the rolling elements securely within the raceways, even during rapid acceleration or vibrations. Compared to simple sheet metal cages, brass withstands higher thermal stresses up to +200 degrees. In terms of design, an external housing seal is recommended, as the open design without integrated seals relies on a clean lubrication environment.
