Four-point contact ball bearings are radial single row angular contact ball bearings with raceways that are designed to support axial loads in both directions. For a given axial load, a limited radial load can also be supported . The bearings are separable, i.e. the outer ring with ball and cage assembly can be mounted separately from the two ...
Get PriceFour point contact bearings are similar in their structure to double row angular contact ball bearings, but are considerably narrower in an axial direction due to only one raceway groove. Since the centres of curvature of the arc-shaped raceways on the inner ring and outer ring are offset relative to each other, the balls are in contact with the bearing rings at four points under radial load.
Get Price2015-6-25 · Four-point contact ball bearings (QJ bearings) are a specific type of angular contact ball bearings. In many applications one QJ bearing is an interesting alternative to a matched set of single-row angular contact ball bearings. Indeed, its space-saving design, the speed capabilities and the load carrying capacity are remarkable.

Get Price2019-6-6 · A better solution nowadays is a single four-point contact ball bear-ing. This bearing utilizes gothic arch race construction for the inner and outer race ball paths to generate four points of contact for each ball. This in turn generates intersecting contact angles that create a large effec-tive pitch diameter to offset any overturning moment load.
