Metric-Size Four Row Tapered Roller Bearings

The performance of four row tapered roller bearings or multi row tapered roller bearings are almost the same as double row tapered roller bearings, but their radial and axial loading capacity are much higher, can carry heavy axial loads in two directions. However, the limiting speed of four-row tapered roller bearing is lower. Usually used as rolling mill bearing arrangements, mainly used by heavy engine machines, such as, in a rolling mill, mining, metallurgy, plastics machinery, large cold and other heavy machinery. CJB can provide customers other tapered roller bearings with special structures, such as sealed tapered roller bearings, etc.

Current product range: Ø d = 150 to 750 mm; max. Ø D = 1200 mm.
Detailed data about the product range can be found in CJB catalogues.
Possibility of delivery bearing types not listed in the catalogues should be discussed with CJB.
