CASTROL PRODUCTS

Castrol Longtime PD 1 universal solid free extreme pressure grease 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.

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
�� for "life" lubrication in some applications
Application
Specifications of antifriction bearing manufacturers must be followed.Maximum performance only if applied unmixed. CASTROL LONGTIME PD greases allow production consolidation of previously used lubricating greases; their high efficiency ensures economical use and hence a reduction of lubricant expenses. Learn More
