WD Rolling Mill bearings include four row cylindrical roller bearings and 4 row tapered roller bearings;
WD four-row cylindrical roller bearingsare used almost exclusively for the roll necks of rolling mill stands, calenders and roller presses. Their friction is low compared with other roller bearings. As they are normally mounted with an interference fit on the roll neck, they are particularly suitable for rolling mill applications where the rolling speed is high.
WD four-row cylindrical roller bearings are normally produced with the C3 or C4 radial internal clearance required for rolling mill bearings. Bearings mounted with a loose fit on the roll necks generally have C2 radial internal clearance.
WD four-row tapered roller bearings are delivered as ready-to-mount bearing units with an axial internal clearance adapted to the actual application. The bearing components must be arranged in the prescribed order and may not be interchanged with components of another bearing.
WD four-row tapered roller bearings having a clearance other than that of the basic design are identified by the designation suffix C followed by a three or four-figure number which is the mean value of the axial internal clearance expressed in Ám .
WD four-row tapered roller bearings are subjected to a unique heat treatment process that enables the bearings to be operated up to +150 ℃ without any inadmissible dimensional changes occurring.
Four-row tapered roller bearings are fitted with either;
Four pressed steel window-type cages
Four steel pin-type cages
