Nye Lubeletter - April 2010
Synthetic Gear Lubricants Gone Green
As the Global Industry moves towards environmentally friendly “Green” lubricants, challenging issues have been created for lubrication in gearing applications. Over the last decade, gears have been pushed to design limits as they are required to run at higher speeds, heavier loads, and for longer periods of time. Along with new materials and improved manufacturing processes, Synthetic Lubricant Technology has helped to achieve these higher industry expectations. Nye has been hard at work on new developments for the demanding gearing applications of tomorrow and the “Green” needs of the future.
Bridging the Gap between Hydrocarbon and Perfluoropolyether Connector Greases
Nye developed Rheotemp™ 761G, a polyurea thickened, medium viscosity, synthetic hydrocarbon grease fortified with a copper passivator and UV tracer for use in electrical contacts. This grease was designed to bridge the temperature gap between NyoGel® 760G and the Uniflor™ 8917 and 8512. In addition to bridging the temperature gap, Rheotemp™ 761G was designed to meet the insertion force and resistance requirements of SAE/USCAR-2, revision 3, the performance standard for automotive electrical connection systems. In the competitive automotive industry, strict connector design requirements such as long life, protection against oxidation and fretting corrosion, optimal electrical performance, and low insertion force are coupled with the mandate to reduce costs. Rheotemp™ 761G helps meet these objectives.
