The 4 row tapered roller bearing adopts two double-raceway inner rings, one double-raceway outer ring and two single-raceway outer rings. There is a spacer ring between the inner ring and the outer ring to adjust the bearing clearance. This type of bearing can withstand higher loads. Large radial load and certain axial load, low limit speed.
It is usually used for steel processing machinery, cold rolling mill.
What material are tapered roller bearing?
