Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.

cylindrical roller bearing can be prevented from tilting roller or rollers each other mill inspections
Cylindrical roller bearing roller internal structure was aligned perpendicularly intersecting each other (which is also cross roller bearings origin of the name), equipped with the interval between the roller cage or isolation block, cylindrical roller bearing can be prevented from tilting roller or rollers each other mill inspections, effectively preventing the increase of rotational torque. Inner or outer cylindrical
roller bearing of the cylindrical roller bearings, the inner and outer rings relative to the axial movement can, so you can use as a free-end bearings. On either side of the inner and outer double-wall, rings on the other side there is a single wall of the cylindrical roller bearings, can withstand a certain degree of axial load direction. General use steel stamping cage, or copper alloy roller bearing solid cage. But there are also some use of polyamide forming cage. Cylindrical roller and raceway line contact bearings. Load capacity, the main radial load. Rolling ring wall friction is small, suitable for high-speed rotation. Roller and raceway line contact or repair offline contacts, radial load capacity, suitable to withstand heavy load and shock load.
