The inner ring and roller neck of four row cylindrical roller bearing should be interference fit. When installed, it should be heated to 80 ~ 90 ℃ and the temperature should not exceed 100 ℃. Otherwis...
Four row cylindrical roller bearings are mainly used in cold/hot rolling mill,bloomer and other steel rolling mill machines.The bearing structure is separate structure. The bearing rings and rollers c...
Carburized bearing steel is also called semi-hardenable steel, which is soft inside and hard outside. The material has a certain degree of "elasticity" for impact resistance. It needs to be carburized...
Rolling bearings are mainly composed of high carbon chromium bearing steel.High-carbon chromium bearing steel is also called fully hardenable steel with the same inside and outside hardness. It is wid...
Four Row Tapered Roller Bearings Four row tapered roller bearings can endure both radial force and axial force without thrust bearings to make the main machine more compact. The inner diameter and the...
Four row cylindrical roller bearings + Thrust Bearings Cylindrical roller bearings inner diameter works together with roll neck to endure radial force. It has the advantages of heavy load, high rotati...
As critical roller bearing of rolling mill, the spare parts of four row cylindrical roller bearings can be replaced, installed, dismounted and cleaned easily. Within the radial installation area, it c...
Steel metal rolling operations usually deform the materials by compressive forces between two constantly spinning rolls. These forces act to reduce the thickness of the metal and change its grain stru...
Modern rolling mills for long products are usually named basing on their products, such as merchant bar mill, rebar mill, TMT bar mill, and wire rod mill, etc. The design of these rolling mills has to...
Angular contact ball bearings have a contact angle, so they can carry significant axial loads in one direction as well as radial load. As the contact angle increases, the axial load carrying capacity ...
