Four row tapered roller bearing

Details

Four row tapered roller bearings are also commonly used roller diameter bearings. This structure has a large bearing capacity and can simultaneously withstand combined radial and axial loads, mainly radial loads. Its radial bearing capacity is about 2.5-3.5 times that of a single row bearing, and it can withstand significant radial and axial loads. Due to structural limitations, its limit speed is relatively low compared to four row cylindrical roller bearings. Four row tapered roller bearings can withstand axial loads in two directions, so they can be used as bidirectional thrust bearings.

Four row tapered roller bearings are mainly used for work rolls, support rolls, and billets of various plate and strip mills. By adjusting the thickness of the spacer ring, the clearance of the bearing can be changed to better adapt to the working conditions.
