Castrol Longtime® PD 1 + PD 2
Castrol Longtime PD 1 + 2 - universal solid free extreme pressure greases for long term lubrication with wide application range.
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 release compounds forming a 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 micro-smoothing of the friction surfaces.
Features
reduction of running-in period, suitable for lifetime lubrication
surface improvement to an extent not possible before
outstanding load carrying capacity
notably decreased coefficient of friction resulting in energy savings
optimum wear protection in high load range
smoothing of existing pitting on damaged components
reduction of noise levels
excellent rust protection, largely prevents fretting corrosion
compatible with all conventional sealing materials and nonferrous metals
| | Uses
For a large field of applications and various difficult operating conditions,
i.e., extreme pressures, vibration, shock loads, wide temperature range and
components that are prone to fretting corrosion. For constant velocity (CV)
joints, ball joints, ball spindles.
For bearings with rotating outer ring and high stresses due to centrifugal load,
e.g. in spreader rolls, roll neck bearings in steel mills; for bearings with changing
rotational directions or slewing movements.
For long-term and lifetime lubrication of heavily loaded bearings in motor
vehicles, wheel hubs, shaker screens, wood and metal routers, machine tool
spindles, spinning spindles, disk drives, high speed looms, robots.
For high speeds up to Dn factors of 1,000,000.
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
