(3) Four row tapered roller bearing
Four row tapered roller bearings are also roller diameter bearings widely used. The type of bearing has a large carrying capacity and can carry the combined radial and axial loads mainly consisting of radial load at the same time. Its radial load capacity is about 2.5-3.5 times larger than single row bearing, and it can carry large radial load and axial load. Due to limited structure, its limit speed is relatively lower than that of four row cylindrical roller bearing. Four row tapered roller bearings can carry axial load in two directions, so they can be used as bidirectional thrust bearings.
Four row tapered roller bearings are mainly used for work rolls and support rolls of various plate and strip rolling mills and roughing mills. Adjusting the thickness of the spacer ring and the clearance of the bearing make such bearing more suitable for the working conditions.
