Abstract
A spherical hydrostatic bearing having a ball mounted in a split socket for substantially friction free movement relative thereto and a linear hydrostatic bearing extending through the ball and having a longitudinal axis coinciding with the longitudinal axis of the ball for permitting substantially friction free sliding movement of a rod. Also, apparatus is provided for at least limiting rotational movement of the ball around the longitudinal axis of the split socket.
