Product Features Sophia Four-row tapered roller bearings Rolling Mill are the most comely roller bearing. The structure bearings have a large bearing capacity & withstand both radial and axial combined loads. Its radial bearing capacity is about 2.5-3.5 times that of single-row bearings, and Sophia Four Row Taper Roller Bearing Rolling Mil can bear large radial and axial loads.replace FAG bearing. Sophia Four-row tapered roller bearings are the most commonly used roller-diameter bearings. This type of bearing has a large bearing capacity and can withstand both radial and axial combined loads. Its radial load carrying capacity is approximately 2.5-3.5 times that of single row bearings, and Sophia Four Row Taper Roller Bearing Rolling Mil can withstand large radial loads as well as axial loads. Sophia Four-row tapered roller bearings accommodate low-speed and medium-speed combined (radial and axial) loads. They are used almost exclusively in roll applications such as rolling mills.
