Product Description
Products description
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.
In four-row cylindrical roller bearings, the rollers are guided between integral or non-integral flanges on the outer ring. The inner ring is without flanges; axial displacement of the shaft in respect to the housing can therefore be accommodated by the bearing within certain limits.
Depending on the application, four-row cylindrical roller bearings can be supplied with a cylindrical bore or a tapered bore. The inner and outer rings may be in one piece or in more than one piece.
Four-row cylindrical roller bearings can also be supplied as sealed bearings, with a seal at one side or at both sides of the bearing. The seals are double lip radial shaft seals. Compared with open bearings, sealed bearings offer the following advantages:
Longer service life.
Reduced grease consumption.
Longer relubrication intervals.
Grease leakage and contamination of the rolling emulsion are prevented.
Sealed four-row cylindrical roller bearings are produced with cylindrical bore; two designs are available.
