CASTROL Longtime PD 2
Industrial Greases and Pastes
Longtime PD 2 can be used for long-term or lifetime lubrication even under the most difficult operating conditions such as extreme pressure, vibrations, shock loads and a wide temperature range in highly loaded rolling and sliding bearings.
Longtime PD 2 can also be used in bearings of spinning and grinding spindles, for gear motors exposed to shock loads, in screening/wood shaping machines and for bearing surfaces of printing plates. These greases are also suitable for bearings with a rotating outer ring and undergoing high stresses due to centrifugal load, e.g. in spreader rolls, roll neck bearings in steel mills, and for bearings with changing rotational directions or slewing movements. They are also used in curved teeth couplings and centralised lubricating systems.
It has extremely low coefficients of friction which is generating energy savings and reduced noise levels.
Longtime PD 2 has exceptional water-resistance, therefore the coating film stays on the surface even in presence of water; even when exposed to the action of hot and chemically active process water.
Castrol Longtime PD greases, the whole product line, are lithium based greases containing highly refined mineral oils and fortified with the Microflux Trans (MFT) additive system. 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 microsmoothing of the 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, a hydrodynamic lubrication film is easier to maintain. This unique physio-chemical reaction achieves a nonsacrificial micro-smoothing of the friction surfaces.
