382044 2077144 Bearing

382044 2077144 Four row taper roller bearings consist of two double row inner rings, one double row outer ring and two single outer rings: one inner spacer is set between two inner rings; two middle spacer rings between three outer rings can adjust clearance.


When the bearings bear bigger radial load, they also can bear axial load at two directions at the same time, but their allowable rotation speed is not high. They are mainly used in rolling bearing of rolling mill. In recent years, four row taper roller bearings with double surface seal ring have been produced and have been widely applied.

Four row taper roller bearings with medium and small size are made of bearing steel; large sized four row taper roller bearings are made of carburizing steel. Hollow roller and pillar cage are adopted for bearings with especially big size, in order to prolong service life of bearings.
