  • Four point contact ball bearing stiffness

    Many methods have been proposed to determine the bearing stiffness. The very compact design of a four-point contact ball bearing may lead to the concern that the load rating of a matched set of two single-row angular contact ball bearings might be comparatively higher. Normally there is almost no difference between the load carrying capacity of ...

  • Four-point contact ball bearings | SKF

    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 ...
