Long-life Oil SM for Heavy-duty Oil Film Bearing

SM.png


This series of products are high-quality oils used for heavy-duty and long-life circulating systems, which are made from deeply refined mineral oil with a variety of multi-effect additives, with a strong and tough oil film that is not easy to damage. They are added with rust inhibitor, antioxidant, defoamer and other additives, and designed for the circulating system of high-speed rod-rolling mill in steel and metallurgical plants.


Major advantages:


         1.Excellent oxidation stability at high temperature: due to the harsh conditions in steel plant, there may be a large amount of water, rolling solution, dirt and boiler scale entering the operation site, and the temperature of the machine body is high. This oil contains special antioxidant, which can effectively cope with harsh lubrication environments, delay the deterioration of oil products, and ensure long service life in extremely high temperature environments. Its replacement interval is several times that of ordinary oil products, saving oil costs.

        2.Excellent oil/water separation: it can easily separate and deposit the water entering the circulating system at the bottom of the tank to discharge, preventing the oil viscosity from decreasing and the oil film bearing capacity being insufficient due to the dilution of water, and maintaining long-term effective lubrication.

       3.Superior wear resistance: the lubrication of rolling mill bearings is to use an oil film to separate the relatively moving rolling surfaces from each other, so as not to fail due to excessive wear caused by rough point contact; the extremely heavy load in startup or shutdown and the contaminated particles may cause wear to the bearings. This oil is specially added with lubricating, anti-wear and anti-EP additives. Its anti-wear performance meets the performance requirements of US Steel 136, which requires extremely heavy-duty circulating oils. All types of oil film bearings, whether hydrostatic, dynamic, hydrostatic-dynamic or the new "TZ" keyless oil film bearings, are maintained in good condition and the maintenance intervals are extended.

       4.Remarkable rust and corrosion resistance: it can effectively resist the corrosion of the body caused by the invasion of a large amount of water or acidic substances, and keep the parts as new for a long time.


Main Application:

        It is recommended to be applied to the circulating system of Morgan Construction Co., Danieli Butrio and other high-speed steel strip mills equipped with two lubrication systems for lubrication protection of oil film bearings, gears and adjusting screws, as well as the circulation system of rolling and back-up roll bearings.

        It is also widely used for the lubrication of various closed gears, bearings with heavy loads or under high temperatures, and oil pressure systems.
