Inner ring for four-row cylindrical roller bearings is consuming parts and should be replaced oftenly.
Cylindrical roller bearings with four or more rows of rollers are used almost exclusively in rolling mills. They have lower friction than other roller bearings and can be successfully used where high speed operation is called for. The low cross-sectional height of cylindrical roller bearings means that the roll necks can have a large diameter in relation to the roll itself.
