A middle liner of a slide guide device for a machine press has a spherical shaped side which fits into a sliding gib attached to a slide. The middle liner slides along a fixed gib at first and second linear surfaces that are at an angle with each other. The combination of self-alignment and smooth movement of the slide is achieved in the presence of an eccentric load acting on the slide. A machine press equipped with such a slide guide device has excellent eccentric load resistance and high working precision. In a further embodiment, a press machine is further equipped with a knockout device having knockout block moving between a pair of guide rails. A plurality of middle liners, each having at least one spherical surface, are positioned between the knockout block and the guide rails. The resulting knockout device provides a stable knockout load with low noise and low energy consumption.
