NSK ROLLING MILL BEARINGS including
Four Row Tapered Roller Bearings
Four Row Cylindrical Roller Bearings
Two Row Tapered Roller Bearings
Angular Contact Ball Bearings
Four Row Cylindrical roller bearings are also popular roll neck bearings providing several benefits.
First,the inner ring is separable from the outer ring and rollers which allows the inner ring to remain with the roll during grinding processes.This assures precise concentricity and negligible run-out providing for high rolling accuracy.Secondly,this design allows for greater radial load carrying and higher operating speeds.Four row cylindricals require a thrust bearing which is usually a two row taper,angular contact ball bearing,or a deep groove ball bearing depending on the thrust load present.

Two Row Tapered roller bearings are very common as the back-up thrust bearing in a rolling mill or as the roll neck in lighter duty rolling mills.Two row tapers are designed in a variety of styles for different applications.Converging bearings (TDI,TDIE,TDIS) consist of one double cone and two single cups possibly with a cup spacer.Diverging bearings (TDO,TDOD,TDOC) consist of two single cones,a cone spacer,and one double cup.
Angular Contact ball bearings are used as thrust bearings for roll necks using four row cylindricals and having lighter load requirements.These bearings can only accept axial loads in one direction so they are used in sets of two with the contact angles diverging.
Four Row Tapered roller bearings are very popular for use on roll necks.Most of these bearings are composed of two double cones (four Inner ring raceways),a cone spacer,two single cups (one at each end),one double cone (the center two raceways in the outer rings),and two cup spacers.They are very effective at operating under heavy radial and axial loads at low to moderate speeds.NSK four row tapered bearings are standardly supplied with carburized rings and rollers and are compatible with industry standards.”Sealed-Clean” bearings are four row tapers with seals for the harshest of operating environments.NSK’s patented design provides the optimum sealing efficiency with only a slight loss of capacity.
