TIMKEN bearing lubrication at low humidity corrosion is very slow

TIMKEN bearing Rust prevention work is poor and work-related corrosion of anti-rust bearings in warehouse management, practice has proved that many different types of bearing corrosion, this is often the most important atmospheric corrosion. When low bearing temperatures or humidity within the Treasury increases, atmospheric moisture condenses in the dew in the packaging materials, TIMKEN bearing surface, forming a thin layer of water (also known as the wet film). If the air contains impurities, such as coal, grain, sand, dust, will reduce condensation on surface tension, promote the formation of water or thick.
TIMKEN bearing corrosion rate and the relationship between the relative humidity of the atmosphere is true linear relation between the relative humidity was very low bearing rusting is slow, but relative humidity is increased beyond a certain value, the corrosion rate suddenly rise, it is called the critical relative humidity. Around the critical humidity in 65%, aluminum 65%,65% iron, zinc 701%, TIMKEN bearings within the Treasury relative humidity of not more than 60%
TIMKEN bearing inspection, should remove oil sealed package, containing 3% acid and oil free kerosene, petrol or cleaning, cleaning and washing outer ring rotation bearing cages, between the rolling elements and raceways, housing to ensure that any residual traces of oil has been cleaned. Clean, every oil flow, in a dry and clean work surface neutral backing, or far infrared heat to dry slowly, after cleaning the TIMKEN bearings. Drying or drying, throughout the process, regardless of the bearing inner ring, cage or out loud, should open.
