The general bearings can withstand temperatures up to 120 degrees Celsius (outer ring measuring a temperature of 100 degrees Celsius). More than times the temperature of the working conditions, should know after a special heat treatment or special materials (heat-resistant) bearings. Bearing if it is often used at a temperature above 120 degrees Celsius, alive when used in a very short, very high temperatures, will be the change of the organization of the bearing material, leading to a reduction in bearing load capacity and service life.
In the rolling mill bearings, blooming mill, hot rolling mill, heat conduction to the roller bearings. If there is no good cooling measures, bearing performance will be affected to some extent or serious total impact.
(1) greased failed to meet the lubrication requirements of bearing mounting impact on the life of the sealed grease lubrication is more reliable and, of course, should be made cautiously choose fat Shen trademarks and harsh assure each use of links to craft requirements. Are using oil lubrication, NSK add a the inclusions ceramic machine axis. What type of bearing seal? . Under the premise of being full foot lubrication requirements, the best public for the Timken bearing supply simple lubrication method and lubricant flow.
 (2) improve the reliability concept, and more emphasis on the mode of the melting of the steel of the bearing, to select the real space in accordance with the needs of environmental degassing steel smelting steel, so that the molten steel and the real space in electroslag Shen repeatedly immersed molten steel real space, etc. as a bearing material.
 (3) are bearing layout choice on because the punching link the rack more difficult corrosion, the cross section changes at and difficult to render when the force set less than the physical link frame of its reliable physical link frame with rivets and reliable sex without entity link frame without rivets, by the combination of the two halves are not as physical link of the entire frame.
