A press system comprising: a frame; a slide element guidable by the frame between a retracted position and an extended position; and a first bearing assembly acting between the slide element and the frame, the first bearing assembly comprising a first bearing housing, having an arcuate, concave guide surface, on one of the slide element and the frame, a first carrier, having an arcuate, convex guide surface, guided in the concave guide surface of the first bearing housing and roller elements (140,144) acting against a first surface on the other of the slide element and the frame to guide movement between the slide element and the frame as the slide element is moved between the retracted and extended positions, wherein a) the first bearing housing is fixedly attached to the one of the slide element and frame, b) the first carrier is connected to the first bearing housing for pivoting movement relative to the bearing housing around a fixed first pivot axis extending through the centers (120, 126) of the arcuate surfaces (118, 124) of the first bearing housing and the first carrier, c) the roller elements (140, 144) are connected to the first carrier for pivoting movement relative to the first carrier around fixed second and third pivot axes (146, 148), that are parallel to the fixed first pivot axis characterized in that d) a center roller element is pivotable around the fixed first pivot axis. a frame; a slide element guidable by the frame between a retracted position and an extended position; and a first bearing assembly acting between the slide element and the frame, the first bearing assembly comprising a first bearing housing, having an arcuate, concave guide surface, on one of the slide element and the frame, a first carrier, having an arcuate, convex guide surface, guided in the concave guide surface of the first bearing housing and roller elements (140,144) acting against a first surface on the other of the slide element and the frame to guide movement between the slide element and the frame as the slide element is moved between the retracted and extended positions, wherein a) the first bearing housing is fixedly attached to the one of the slide element and frame, b) the first carrier is connected to the first bearing housing for pivoting movement relative to the bearing housing around a fixed first pivot axis extending through the centers (120, 126) of the arcuate surfaces (118, 124) of the first bearing housing and the first carrier, c) the roller elements (140, 144) are connected to the first carrier for pivoting movement relative to the first carrier around fixed second and third pivot axes (146, 148), that are parallel to the fixed first pivot axis characterized in that d) a center roller element is pivotable around the fixed first pivot axis. a) the first bearing housing is fixedly attached to the one of the slide element and frame, b) the first carrier is connected to the first bearing housing for pivoting movement relative to the bearing housing around a fixed first pivot axis extending through the centers (120, 126) of the arcuate surfaces (118, 124) of the first bearing housing and the first carrier, c) the roller elements (140, 144) are connected to the first carrier for pivoting movement relative to the first carrier around fixed second and third pivot axes (146, 148), that are parallel to the fixed first pivot axis characterized in that d) a center roller element is pivotable around the fixed first pivot axis.
