Bearing assembly

A bearing assembly for mounting a bearing journal of a rotatable roll, the bearing assembly comprising:

• a bearing housing, a spherical bearing element in the bearing housing for supporting the bearing journal, and the bearing journal being received in the spherical bearing element in the housing;
• means at the spherical bearing element for fixing the bearing journal in the bearing housing with respect to the direction of the longitudinal axis of the bearing assembly;
• a base;
• two axial guide elements connecting the bearing housing to the base;
• the axial guide elements comprising guide rods which engage both the bearing housing and the base and which include sliding surfaces thereon, the sliding surfaces extending parallel to the longitudinal axis of the bearing assembly for enabling the bearing housing to slide axially with respect to the base due to changes in the axial length of the roll and resultant changes in the position of the bearing journal of the roll, the guide rods being arranged at mutually opposite regions around the circumference of the bearing housing;
• the two guide rods being positioned to together define a guide plane, and the guide plane lying substantially perpendicular to the direction of the force transferred by the guide rods from the bearing housing to the base.
