Four Row Taper Roller Bearing

Four row tapered roller bearing is successfully used in the bearings of the rolling mills with a low to medium rolling speed around the world. The bearing can not only bear radial load, but also bear the axial load appeared in the applications due to its design, and the bearing generally does not need additional thrust bearing. This means that the roll neck can be relatively short, and the roll bearing seat on both sides of the roll neck can adopt the same design. In terms of the design of the product, the bearing must be installed as complete bearing mounted on the roller bearing seat.

In order to quickly replace rollers, four row tapered roller bearing on the roll neck must be loose fit. The disadvantage of loose fit is the inner ring can move on its base under the main load conditions, thus usually leading to the wear of base caused by the bearing ring with higher hardness. For the sake of reducing wear, the bearing has the spiral groove in the inner hole and the oil groove on the side of inner ring. The oil groove sends the lubricant to the contact surface of the inner ring and base. In addition, the oil groove can absorb the wear particles. Four row tapered roller bearing is widely used in car, rolling mill, mining, metallurgy, plastics machinery, large cold and hot rolling mill and other heavy machinery.
