Radial Spherical Plain Bearings

Radial spherical plain Bearings

Radial spherical plain bearings have an inner ring with a sphered convex outside diameter and 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 possible at relatively slow sliding speeds.

Radial spherical plain bearings requiring maintenance have the sliding contact surface combination steel-on-steel. Bearings with this sliding contact surface combination require regular relubrication. The high wear resistance of the sliding surfaces makes these bearings especially suitable for bearing arrangements where heavy loads of alternating direction, shock loads or heavy static loads have to be accommodated. Bearings which have cylindrical extensions at both sides of the inner ring are intended for applications where normally spacer sleeves are arranged at either side of the bearing, or are specially designed for the bearing arrangements of hydraulic cylinders.

WSA 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 WSA should be contacted for advice in such cases.

For bearings which have an outer ring with a butt joint, a deliberate fracture or which is axially split, the internal clearance can only be properly checked if the bearing is first inserted in a sleeve. The sleeve bore diameter should equal the nominal outside diameter of the bearing; the diameter tolerance limits are 0/-0,004 mm.
