ABSTRACT:
Located in a stationary frame is a cylinder-piston unit, the piston of which is adapted to displace the bearing housing of a roll in a paper-making machine at right angles to the longitudinal axis thereof. The bearing housing is guided in the frame with the aid of linear guide-elements. The radial play between the piston and the cylinder-bore is greater than the transverse play between the said linear guide-elements. Furthermore, the axial length of the piston is less than the depth of the cylinder-bore. Whenever the cylinder-piston unit is relieved of its load, and the cylinder thus returns to its position of rest, it is centered in the cylinder-bore by means of a centering device.
