  • The Lowdown On Lubricants For Rolling Bearings
    adequately at the stated temperature limit. Very low temperatures may result in excessive rotating torque or insufficient oil bleed from the grease pack. At very high temperatures the rate of oxidation (deterioration) of the grease will accelerate and evaporation losses will be magnified. (Refer...
  • The attraction of Ferrofluid Bearings
    to control the speed of the bearing unit. Operation at elevated temperatures can as well alter lubricating-grease properties and shorten bearing life. In contrast, ferrofluid bearings that carry loads on a film of oil don't suffer. The attraction of Ferrofluid Bearings | Machine Design. Skip to Content...
  • Predicting lube life
    10°C rise. High temperatures promote oxidation and raise oil evaporation rates and oil loss by creep, all of which accelerate grease drying and shorten life. Grease life LG, can be estimated for operating temperatures above 70°C with moderate loads and no contamination by: log LG = -2.60+2,450/(T+273...
  • Lubricants For Semiconductor Manufacturing Equipment
    Aerospace manufacturers long ago solved the problem of lubricant outgassing, contamination, and starvation. Their work is now reaping benefits in the semiconductor industry. Ultrafiltration removes microscopic contaminants from oils and greases and homogenizes agglomerated thickener in grease...
  • Into the Mix: Centralized Lubrication Technology
    in today's (and tomorrow's) industrial plants. SYSTEM PROFILES. Centralized lubrication technology generally falls under two broad "umbrella" categories: total loss and circulating oil systems. In total loss systems friction points are always supplied with fresh lubricant (oil, fluid grease, or grease...

Magnetic fluids, also called ferrofluids, are advanced materials that can solve complex engineering problems — in particular sealing rotary shafts. They offer a cost-effective solution to environmental and hazardous-gas sealing in a wide variety...
