High-performance synthetic gear oil used in rail traffic and mechanical engineering applications, for long-term use and in extreme climate conditions. The “Microflux Trans” additive system protects and improves the surface profile of gear teeth. Fully synthetic gear oils for the lubrication of drive units in rail-borne traffic and machine construction at extreme climatic conditions. High load-carrying capacity Microflux Trans additive system minimizes wear and friction Excellent low temperature performance Good corrosion protection Optigearspan RO spanare a fully synthetic multigrade high performance gear oil incorporating Microflux Trans additives. They offer optimum wear protection at low starting temperatures but are suitable for use across a wide temperature range.Optigear RO are suitable for use in spur gearings, bevel gear pairs, conical (hypoid) and all types of rolling bearings. They are available in dip lubrication form for high speeds as well as injection and oil mist lubrication.
