Rolling mill bearings
Four row cylindrical roller bearing is also called rolling mill bearing which especially applied to rolling mill in metallurgical industry required high speed and precision.
Main Characteristics
a. The maximum dynamic load rating can be achieved with a limited mounting space;
b. They are applicable for high speed operation;
c. They permit more accurate limiting tolerances;
d. Both inner ring and outer ring assembly (outer ring with a set of rollers) are interchangeable, which is helpful for quick roll
replacement;
e. They can only accommodate radial load.
Application:
Four row cylindrical roller bearing is also called rolling mill bearing. Its main application is in rolling mill for the production of steel plates, sheets, channels, H-beam, angles, flats, round bars, deformed bars, wires, coils and rails, also for stainless steel, aluminum and copper products.
