Four-point contact ball bearings can handle radial, thrust and moment loads simultaneously, saving space, weight and cost by eliminating the need for a second bearing. They are generally used for slow to moderate-speed applications, or where oscillatory movement is sufficient to cause the balls to make one or more revolutions. A new white paper from Kaydon Bearings explains how four-point contact bearings work, their advantages, and design considerations when using them.
