  • 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 ...
