Abstract

The invention concerns an annular multi-row bearing with shaped-wire races with an inner and an outer race, each of which constitutes part of the tracks for the rolling components, and with rolling components accommodated between them. The particular object is, in addition to others, to create a bearing that, although stable, is resilient enough when transverse forces occur to allow both races to twist in relation to each other within certain limits, avoiding stress. The invention attains this in that the contact or rolling surfaces between the races and the rolling components are provided with a contour that deviates from the rectilinear and mutually surrounds itself and in that these contact surfaces are shaped and/or positioned such that there is a four-point bearing in each track. This principle can be embodied with either ball bearings or roller bearings, whereby only three shaped wires are preferably employed. The angles of support range, depending on the type of bearing, between approximately 30.degree. and approximately 90.degree..
