Description

Castrol Tribol™ GR 100 PD (previously called Longtime™ PD) is a range of lithium based greases containing highly refined mineral oils, enhanced 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 micro-smoothing of the friction surfaces.
Under severe load, components of the MFT additive combination are activated, initiating an improvement of surface friction characteristics through plastic deformation. The products of that organic reation 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. This means that the load carrying area is improved and a hydrodynamic lubrication film is easier to maintain. This unique physio-chemical reaction achieves a non-sacrificial micro-smoothing of the friction surfaces.

Application
The Tribol GR 100 PD Range can be used for long term lubrication even under the most difficult operating conditions such as extreme pressure, vibrations, shock loads and a wide temperature range (-35°C to 140°C / -31°F to 284°F) in highly loaded rolling and sliding bearings. Typical applications include bearings of spinning and grinding spindles, gear motors exposed to shock loads, screening / wood shaping machines and 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. Examples are spreader rolls, roll neck bearings in steel mills, and bearings with changing rotational directions or slewing movements. They are also used in curved teeth couplings and centralised lubricating systems.
Tribol GR 100-0 PD and 100-00 PD can be used as semi-fluid grease lubricants in gears such as flange, drum-type and worm gears. These two products are also suitable for use in gears without oil-tight enclosures, gear wheels and rolling bearings with a grease reservoir
