Four- row tapered roller bearings are one kind of roll neck bearings, their radial and axial loading capacity are high, can carry heavy axial loads in two directions, and their radial loading capacity is 3 times heavier than single-row tapered roller bearings, but limiting speed is lower.
Four-row tapered roller bearings are suitable for accommodating great radial forces and are most widely used in the roll neck areas of rolling mill equipment. Their inherent benefit is the ability to provide an application with maximum load ratings while at the same time working within a smaller space requirement. maximum capacity in minimum space, combining the inherent high-load, radial/thrust capacity and direct/indirect mounting variables of tapered roller bearings.
