The tapered roller bearings can only pass one-way axial load, so as to pass the opposite direction of the axial load on the need install another with symmetrical tapered bearing roller bearings .Tapered roller bearings is the largest amount of single row tapered roller bearings. In the car’s front wheels in recent years to spend the small size of the double row tapered roller bearings. Four tapered roller bearings used in large-scale cold rolling mill and other heavy machines.

1.The material of inner rings and outer rings are adopted high purity of bearing steel which is extremely low in oxygen content (<6PPM), they are also adopted the special heat treatment to get the excellent material structure and lengthen the bearings’ using life.
2. Adopted high quality of bearing steel rollers to increase the bearings’ load.
3. It  has got enough intensity, and could not make the grease aging, it has the traits of self-lubrication and excellent heat-resistant.
