Castrol Optigear? BM
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.
Advantages
? shortens running-in periods and allows running-in of lubrication surfaces under full load from the start
? outstanding load carrying capacity
? optimum wear protection in high load range
? excellent anti-wear properties
? smoothing of existing pitting
? surface improvement to an extent not possible before
? increase of supporting surfaces and load carrying capacity (70 - 80% after initial run-in)
? reduction of noise levels
? extreme long oil drain intervals
? low foaming tendency
? extremely low coefficient of friction resulting in energy savings
? compatible with nonferrous metal
? compatible with paints and conventional seal materials
? excellent corrosion protection
? exceeds AGMA specifications 250.04 for EP gear oils Castrol Industrial Americas

Product Data
Usage
In all types of industrial gears, especially operating under extremely heavy loads, even
where conventional EP oils fail:
? gears exposed to high sliding friction and high Hertzian surface pressures up to 2000
N/mm2 (elevators, rolling mills, belt conveyors, extruders, vibrating equipment,
crushers, high speed looms, rear axles, separators
? eccentrics, cam shafts, planetary gears
? variable speed drives (PIV)
? hypoid gears (API-GL5/GL6)
In all types of bearings, especially for spherical roller bearings, full complement
cylindrical roller bearings, thrust bearings
For sealed gear couplings
Cost-benefit offered by MICROFLUX TRANS additive technology
? extended lifetime of machine elements and wear parts, lower maintenance and labor
costs by minimized wear and friction
? full load operation within shortest time, virtually eliminating the running-in period
? lower costs for lubricants and waste oil disposal because of significant extensions of
both service life and relubrication intervals
? energy savings due to reduced coefficient of friction, lower temperature of lubricant
and component, improvement in operating efficiency
? product consolidation, i.e. simplification and reduction of lubes and spare parts
? reduction of noise resulting from high frequency stick-slip
? for "life" lubrication in some applications
Application
Viscosity recommended by equipment manufacturers must be followed. Miscible with all
unleaded gear oils based on mineral oils.
Maximum performance only if applied unmixed.
Castrol Optigear BM oils can be filtered in all common filter systems and separators due
to their homogeneous, oil soluble additives.
Attention: Not for use in synchronized gears and for limitedslip/self-locking differential
gears.
MICROFLUX TRANS? registered trade mark of a patented Castrol additive combination
for performing surface engineering in tribological systems.
