The four row tapered roller bearing with cylindrical bore is designed to maximize the load capacity with minimum space, and is widely used for roll neck of lower, medium speed rolling mills.
The bearing of this type is made up of one double outer ring, two single row outer rings, two double inner rings and inner ring spacer/outer ring spacer.
Since each component is not interchangeable, it is necessary to assemble each component as specified with care taken to the matching marks marked on the bearing.
Applications: Low- and medium-speed rolling mills
