Abstract
A support for a reciprocating ram wherein a plurality of rollers having angularly related generally cylindrical support surfaces are mounted in a fixed location and the ram is provided with planar surfaces having the same corresponding angular relationship wherein the weight of the ram is utilized to maintain the planar surfaces in contact with the generally cylindrical support surfaces during reciprocal movement of the ram with dampening means being provided to minimize vibrations. An additional force is applied to the ram to ensure a rolling relationship between the planar and generally cylindrical surfaces at all times during the reciprocal movement.
