Technical information on Four point contact bearings

Four point contact bearings are particularly suitable where:

• Predominantly axial loads must be supported
• The axial design envelope is not sufficient for double row radial angular contact ball bearings
• Radial forces must be supported by a separate radial bearing
• Axial forces occur in both directions and a close axial clearance is required in conjunction with a small bearing width, e. g. in gearbox engineering
