Castrol Optigear BM- solid-free gear oils for extremely high pressures containing a newly
developed additive combination. Designed to reduce wear caused by surface fatigue,
pitting, spalling, scuffing, scoring or irregularities during running-in period also where
conventional EP gear oils or oils with solid lubricants fail.
MICROFLUX TRANS® (TRANS=TRiple Action Non-sacrificial Surface engineering)
improves friction surfaces to an extent not possible with normal machining processes and
conventional EP lubricants. In a tribological system the polarized MICROFLUX TRANS
additives instantaneously create a passive film on friction surfaces before friction occurs.
At a given load level, the MICROFLUX TRANS additives creates resistant protective layer
on friction surfaces. Under severe load, components of the MICROFLUX TRANS 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 MICROFLUX TRANS are long-chained compounds with
excellent lubricity and adhesion. The load carrying area is improved, a hydrodynamic
lubrication film is easier to maintain. This unique physio-chemical reaction is CASTROL
surface engineering and achieves a non-sacrificial micro-smoothing of the friction
surfaces. The MICROFLUX TRANS 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.
