Product Description

spherical bearings have an inner ring with a sphered convex outside diameter and an outer ring with a correspondingly sphered but concave inside surface. Their design makes them particularly suitable for bearing arrangements where alignment movements between shaft and housing have to be accommodated, or where oscillating or recurrent tilting or slewing movements must be permitted at relatively slow sliding speeds. HYJG® maintenance-free spherical plain bearings incorporate special sliding layers of modern materials which have very low friction. The bearings can be operated without maintenance. They are used for applications where long bearing lives are required without maintenance, or where operating conditions are such (e.g. inadequate or total absence of lubrication) that the use of steel-on-steel bearing is inadvisable. The maintenance-free bearings are primarily intended for applications where loads are heavy and have a constant direction. They have only limited ability to take up alternating loads and HYJG® should be contacted for advice in such cases.
