Publish Time:2018.05.09


The four row tapered roller bearings are composed of two double row inner rings , one double row outer ring and two single outer rings. There is a spacer between the two inner rings.There are two spacers between the three outer rings to adjust the clearance.

The small and medium size four row tapered roller bearings are made of bearing steel . Large four - row tapered roller bearings are made of carburized steel. Especially large size use hollow roller and stanchion cage, in order to increase the service life of the bearing.

Four row tapered roller bearings are generally used pressed sheet-steel cage. The especially large size bearing must use welding type stanchion cage. 

Four row tapered roller bearings are generally P0 tolerance. But according to the user needs we can also produce the higher tolerance bearing.

When bearing a large radial load, the four row tapered roller bearings can sustain two directions axial load , but the bearing's allowable speed is not high , it mainly used in rolling mill.
