Joint Bearings

A Joint Bearing in Which a Rolling Member Has Been Designed in such a Way that Relative to the Inner Race Track and Outer Race Track Representing a Circular Arch, Four Contact Points are Obtained, the Rolling Member is Associated with a Central Cylindrical Portion and Carrying Portions Which Adjoin It At Both Ends, and Has An Outer Contour with a Radius Which is Osculated Relative to the Inner Race Track and the Outer Race Track, So that a Relatively Small and Compact Joint Bearing is Formed Which Permits Both An Angular Movement and a Rotational Movement While Reducing Friction. the Four-point Contact Permits Accurate Guidance of the Rolling Members and Eliminates the Need for Guiding Edges
