Abstract: An assembly for supporting and guiding a movable member of a machine along an axis "X" relative to a support member of the machine. The assembly includes first and second slide surfaces on the support member lying in planes which intersect with each other and extend parallel to the "X" axis, a pair of pneumatic bearing pads are fixed to the movable member and are slidable on respective slide surfaces. A third slide surface is formed on the support member and extends parallel to the "X" axis in a plane inclined to the planes including the first and second slide surfaces. A third bearing pad is fixed to the movable member and is slidable on the third surface in an arrangement to balance the loads exerted by the first and second bearing pads.
