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.

FAG bearings Crossed roller bearings use
Crossed roller Stainless steel slewing bearing FAG, their roller between the inner ring and the outer ring, the interval crosswise arranged at right angles to each other. They can withstand the load from all directions (eg axial thrust load or momentum, etc.). Due to the roller and track status quo into contact with the surface, therefore, FAG bearings under load and the elastic deformation of unlikely. FAG Bearings of this type are widely used in industrial automation, such as robots, machine tools and medical facilities, and need high rigidity, compact and still ensure accurate high speed of occasions.
In cross roller bearings FAG, due to cylindrical roller at 90 ° to the surface of the V-shaped groove scroll through the spacer retainer is arranged perpendicular to each other, so a cross roller bearings can bear radial load, axial load and moment load and other loads in all directions. Inside and outside the ring size is the minimum possible, in particular, is close to the limit of very thin type compact size, and high rigidity, so the most suitable for the industrial robot joints or rotating parts, machining centers rotary table, manipulator rotating parts, precision rotary tables, medical equipment, measuring instruments, IC manufacturing equipment and other purposes.When we use ntn bearing, when the temperature is very high if we find the case, then quickly stop the operation of equipment, and then find out the causes and the solutions provided in accordance with the above-mentioned processes, but may be due to different reasons bearing heating, So, to solve in different ways, so we should treat specific conditions, with the help of the technical staff to complete.
