NSK rolling mill bearings–As to NSK rolling mill bearings, they mainly refer to angular contact ball bearings, four row cylindrical roller bearings, four row tapered roller bearings, two row tapered roller bearings. In the following I will introduce all NSK rolling mill bearings to you separately.

NSK angular contact ball bearings used as thrust bearings fo r 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.

NSK four row cylindrical roller bearings as the most common type of NSK rolling mill 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 fo r high rolling accuracy. Secondly, this design allows fo r 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, o r a deep groove ball bearing depending on the thrust load present.

NSK four row tapered roller bearings are very popular fo r 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 two row tapered roller bearings are very common as the back-up thrust bearing in a rolling mill o r as the roll neck in lighter duty rolling mills. Two row tapers are designed in a variety of styles fo r 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.
