Rolling Mill Bearing

Four row cylindrical roller bearings and four row tapered roller bearings are the two main rolling mill bearings.

Four row cylindrical roller bearings consist of tapered inner and outer ring raceway, the tapered rollers are arranged between them. Four row cylindrical roller bearings are separate type bearing, it is widely used in automobiles, rolling mills, mining, metallurgy, plastics machinery and other industries.

The performance of the four row tapered roller bearings is similar to the double row tapered roller bearings,but relative to the double row tapered roller bearings, it can withstand greater radial load and has a lower limit speed. Four row tapered roller bearings are mainly used for heavy machinery, like rolling mill.
