Types and applications of ultra-high temperature greases

Super high temperature grease products are made by thickening mineral oil with inorganic thickener, and adding high temperature antioxidant, extreme pressure agent, anti-rust agent, etc. Super high temperature grease products have high temperature resistance (PM600) extreme pressure, good thermal stability, acid and alkali resistance, oxidation resistance, excellent performance, long life, high performance oil film strength. Super high temperature grease is suitable for bearings of medium and high temperature, heavy load (166) mechanical equipment. Such as: anti-wear bearings, roller bearings, high temperature bearings and transmission lubrication parts, motor bearings, blowers, reducer, cement brick kiln spindle, bleaching and dyeing machine, high temperature furnace, boiler transmission parts, textile printing and dyeing machine, steam engine and dryer bearings, tensioning machine chain, paper and corrugated machinery and other high temperature transmission fields.
Super high temperature grease products usually have the following characteristics:
(1) Super high temperature grease can maintain the normal operation of the parts at a high temperature of 300 °C.
(2) Super high temperature grease has super extreme pressure resistance characteristics, oil does not melt at high temperature, no splash, good wear resistance, and strong load capacity.
(3) Super high temperature grease can generate a high concentration of polytetrafluoroethylene lubrication protective layer, and continue to lubricated good oil film strength at high temperatures.
(4) It will not dry out or form harmful impurities under high temperature and high load.
(5) Super high temperature grease has good rust resistance and water resistance, can effectively resist salt water and most cleaners, acid and alkali chemical corrosion.
(6) Super high temperature grease has a longer life than ordinary synthetic grease.
Commonly used high-temperature grease products include the following seven categories:
1, boron nitride high temperature grease
Suitable for high temperature bearings, bushings, bolts and sliding parts lubrication and assembly wear lubrication, temperature resistance up to 800℃.
2, polyurea grease
Suitable for all walks of life under high temperature, medium, low speed, high load continuous operation of mechanical equipment lubrication, does not focus on carbon.
3, high temperature water resistant grease
High temperature water resistant grease is suitable for lubricating bearings in iron and steel, mining, machinery, transportation and other industries under high temperature, heavy load and serious moisture.
4, complex calcium sulfonate base grease
It is widely used in metallurgy, automobile wheel bearings, paper making, mining, plastic extrusion and textile industries under high temperature water and heavy load mining conditions of equipment lubrication, can be used in the range of -30℃~220℃ for a long time.
5, molybdenum disulfide (1850) high temperature grease
Suitable for high load bearing (PM600), gear, chain, guide rail, spline shaft, screw lubrication, temperature resistance up to 350℃.
6, bentonite high temperature grease
Suitable for lubrication of sliding or rolling bearings, gears, cams, guides and chains at low and medium speeds under high temperature conditions; For the lubrication of high temperature bearings, such as ovens (PM1400L), high temperature conveyor belts, tenters and hot fans. The temperature can reach 260℃.
7, graphite (156) high temperature grease
Suitable for lubricating bearings, bushings, gears, chains, turntables, guide rails, fasteners, couplings and automotive plate springs, with a maximum intermittent temperature resistance of 500℃. (2023-11-06)
