Four-Point Contact Ball Bearings
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 inner ring halves.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 be supported. These bearings take up considerably less axial space than double row bearings.
A four-point contact ball bearing makes it easy to simplify machine designs that have a combination of radial, thrust and moment loads because it can handle all three simultaneously. They are primarily used for slow to moderate-speed applications, or where oscillatory movement is predominant.A single four-point contact bearing usually makes a second bearing unnecessary,which provides some very important benefits.
