Castrol OptigearTM BM are solid-free high performance gear oils containing the additive combination Microflux TransTM (MFT). Designed to reduce wear caused by surface fatigue, pitting, spalling, scuffing, scoring or irregularities during running-in period and during normal operations.
Microflux Trans (TRANS=TRiple Action Non-sacrificial Surface engineering) improves friction surfaces to an extent not possible with normal machining processes and conventional Extreme Pressure (EP) lubricants. In a tribological system, the polarized MFT additives instantaneously create a passive film on friction surfaces before friction occurs. At a given load level, the MFT additives create a resistant protective layer on friction surfaces.Under severe load, components of the MFT additive combination are activated and diffuse into the surfaces initiating an improvement of their friction characteristics through plastic deformation. The organic reaction products become a component of the tribopolymer system. Unlike the case with conventional lubricants, the tribopolymers
formed by MFT are long-chained compounds with excellent lubricity and adhesion. The load carrying area is improved and the hydrodynamic lubrication film is easier to maintain. This unique physical-chemical reaction is Castrol surface engineering and achieves a non-sacrificial micro-smoothing of the friction surfaces. The MFT additive technology provides optimum wear protection and an extremely low coefficient of friction even under extremes of pressure, vibration, shock loads, at high or low speeds or varying operational conditions.
Optigear BM gear oils are in conformity with and even exceed the requirements of DIN 51517 part 3 CLP and AGMA specifications 9005-D94 for EP Gear Oil
