The Design of Rolling Bearing Mountings

Lubrication, sealingIn spite of the high loads and the low speeds it wouldbe possible to lubricate the cylindrical roller bearingswith grease. However, the spherical roller thrust bearingsmust be oil-lubricated. Therefore, all bearings aresupplied with oil by means of a central lubricatingsystem. The oil flow rate per straightening roll unit isabout 10 l/min.At the spherical roller thrust bearing end the unit isclosed by a cover. At the shaft opening in the directionof the straightening roll two laterally reversed, greaselubricatedseal rings prevent oil escape and penetrationof contaminants into the bearings.110: Horizontal straightening rolls157 FAG
