This re-duces friction and consequently theaxial forces produced when axial dis- placement takes place. Relubrication of non-locatingbearings Non-locating bearings, where axial displacement takes place along the shaft or pin, should always be relubri- cated via the shaft and bearing inner ring (

To obtain a long service life with spher-ical plain bearings and rod ends requir- ing maintenance, they must be relubri- cated. Used grease together with wear debris and any contamination should be removed from the contact zone and be replaced by fresh grease.The relubrication interval should bedetermined when performing the bear- ing calculation. The frequency of relu- brication is of decisive importance for the attainable service life and depends on many factors including• the magnitude of the load,• the type of load, • the angle of oscillation, • the frequency of oscillation, • the operating temperature • the sealing arrangement and • other environmental conditions.Long service lives can be attained whenthe following relubrication conditions are observed:• the same grease is used as originallyapplied;• the relubrication should be carriedout at the operating temperature;• the bearing should be relubricatedbefore a long interruption in operation occurs, e.g. before construction machinery or agricultural equipment is laid up. Storage SKF spherical plain bearings and rod ends are treated with a preservative before they are packaged. They can, therefore, be stored in their original packages for several years. However, the relative humidity in the storeroom should not exceed 60 %.
