Four-rows tapered roller bearing, the performance of this type of bearing is basically the same as that of double-row tapered roller bearing, but the radial load is larger than that of double-row tapered roller bearing, and the limit speed is slightly lower.

It is mainly used for heavy machinery. Compared with open structure bearings, multi-sealed double and four-row tapered roller bearings can prolong bearing life and save lubricant consumption.

Tapered roller bearings are widely used in automobiles, rolling mills, mining, metallurgy, plastic machinery and other industries.

This type bearing mainly used in heavy truck and heavy machine.
