Introduction of Four-row Cylindrical Roller Bearing

Four-row Cylindrical Roller Bearing is also often used as roll bearing. Compared with Four-row Tapered Roller Bearing with the same cross section the rated load is higher. This kind of bearing can only bear radial load. It can bear axial load only when matched with other thrust bearing. It consists of two structures including cylindrical bore and tapered bore.

The inner raceway of Four-row Cylindrical Roller Bearing is cylindrical. The outer ring with roller can be separated easily with the inner ring. It is easy to install and disassemble when the bore is matched tightly with the roll neck and relative sliding can be avoided on the surface of the bore and roll neck. Because the roller and the raceway are both cylindrical comparatively high processing precision can be obtained. And the friction of the bearing is lower than other type of roller bearing so the Four-row Cylindrical Roller Bearing is especially applicable on roller with requirement for high precision and speed such as wire rolling mill, mould mill and cold sheet mill.
