 Rolling mill bearing

Bearings in the Rolling Mill Bearings section are designs of tapered roller and cylindrical roller types, both radial and thrust, that have been specificallly designed  for rolling mill applications.
These bearing types are Line Shaft & Table Roll Cylindrical, Multirow Cylindrical and Tapered Roller Bearings for work and backup rolls, Cluster Mill Radial Bearings, Rollneck Thrust Bearings, and Screwdown Thrust Bearings.
Our rolling mill bearing:
1. Four row tapered roller bearing
2. Four row cylindrical roller bearing
3. Two row tapered roller bearing
4. Angular contact ball bearing
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.
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 if styles for different applications. Converging bearings(TDI,TDIE,TDIS) consist of one double cone and two single cups possibly with a cup spacer. Driverging bearings(TDO,TDOD,TDOC) consist of two single cones,a cone spacer, and one double cup.
