SKF/Global Tapered Roller Bearings, Four-row - BT4B 332720/HA4 134497012

Four-row tapered roller bearings (fig) are used successfully worldwide for rolling mill bearing arrangements where rolling speeds are slow to moderate. Because of their design they are able to take up those axial loads which occur in such applications in addition to radial loads and generally no separate thrust bearings are required in such arrangements. This means that the roll necks can be relatively short and the chocks at both sides of the roll can have the same design (fig).
