A press die set includes a hollow cylindrical guide bush mounted on a punch holder, a cylindrical retainer received within the guide bush, and a columnar guide post vertically mounted on a die holder and received within the retainer. First right angle grooves are formed on the outer surface of the guide post parallel to a longitudinal axis of the guide post. First planar surfaces are formed on an outer surface of the guide post parallel to the longitudinal axis of the guide post and perpendicular to a radius of the guide post. Second right angle grooves are formed on the inner surface of the guide bush parallel to a longitudinal axis of the guide bush. Second planar surfaces are formed on the inner surface of the guide bush parallel to the longitudinal axis of the guide bush and perpendicular to a radius of the guide bush. Cross roller bearings are positioned between the first and second right angle grooves, and plain roller bearings are positioned between the first and second planar surfaces.
