Oil film bearing of steel rolling working condition

General used for roll bearing oil film bearing of steel rolling, condition is very bad, on the one hand speed and load change is big, big impact vibration, some mill positive and reverse frequently, the dynamic pressure oil film forming stability, easy cause dry friction or boundary lubrication, damage to the bearings; On the other hand in the cooling water splash, tin oxide under the working conditions, high temperature, the outside pollutants ( Water, moisture, dust, etc. ) Inevitably enter the lubrication system, make the oil pollution, even emulsification, reduces the oil film strength, easy to damage the bearing. Oil film bearing is a bearing roller operation of key components, manufacturing accuracy requirement is high, the price is expensive, so the oil film bearing oil paper very strict quality requirements, mainly: (1) Good emulsification resistance, can quickly in the normal operation of the separation of oil in water; 2) Good anti-wear and extreme pressure performance, in oil mixed with a small amount of water, can still keep the carrying capacity and antiwear performance, extend the service life of bearing; 3) Good, rust and corrosion resistance; 4) Good viscosity-temperature characteristics, when the bearing temperature fluctuations can still achieve normal lubrication; 5) Good foam resistance; 6) Good oxidation stability, prolong the service life of the product; 7) Good filterability and hydrolytic stability.
