Angular Contact Ball B. FAG 7218 -B-MP-UO

The FAG 7218 -B-MP-UO angular contact ball bearing (90x160x30 mm) accommodates combined radial and axial loads and enables play-free bearing pairs.

The FAG 7218 -B-MP-UO from FAG is a single-row rolling bearing made from standard bearing steel (100Cr6) with a 90 mm bore, 160 mm outside diameter and 30 mm width. Single-row angular contact ball bearings transmit combined loads in which radial forces and single-sided axial forces occur simultaneously. Thanks to the open design without seals, the bearing can be integrated directly into oil- or grease-lubricated housings. The bearing is manufactured to tolerance class P0/PN or ABEC 1 with standard radial clearance.

What loads can the 7218 -B-MP-UO angular contact ball bearing accommodate?

The rolling bearing is designed for rotating shafts that must accommodate high radial forces and simultaneously directed axial forces. Such bearing arrangements are found in combined load conditions in general mechanical and plant engineering. As a single-row angular contact ball bearing, by design, can only accommodate axial forces in one direction, the shaft always requires a suitable mating bearing or installation in pairs.

What are the advantages of the 40-degree contact angle and the UO adjustment?

The nominal contact angle of 40 degrees gives the bearing arrangement a high axial load-carrying capacity in one direction. The designation UO stands for a universally adjustable single bearing which, when mounted in pairs in an O or X arrangement, remains free of play without the need for additional adapter rings. The guided brass cage ensures low-vibration operation of the rolling elements. As the bearing is open at both ends, the surrounding structure must protect against the ingress of dirt.
