Castrol Tribol GR 100-2 PD

Castrol Tribol GR 100-2 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, and 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 reaction 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.

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

Compared to conventional greases, the Castrol Tribol GR 100-2 PD Grease provides the following advantages:

• High load-bearing capacity – extends the operating period under high loads leading to optimum wear protection
• Superior lubrication and surface smoothing effects due to MFT can reduce failures, leading to less downtime and repair work. PD technology can prolong the life of damaged components
• Establishment of a protective layer of MFT – this additive system can effectively increase the load-bearing area, reducing unit pressures, operating temperatures and wear, increasing the service life of both parts and lubricant
• Improved bearing surfaces for longer service life result from the ‘running in’ effect of MFT
• Extremely low coefficients of friction – generating energy savings and reduced noise levels
• Multi-functional – Tribol GR 100-0 PD and 100-00 PD are highly recommended for anti-friction bearings with grease reservoirs and leaky gearboxes.
• Easily pumpable in central lubrication systems – does not channel on gears running at high speeds when using 100-0 PD 0 and 100-00 PD

Storage:

All packages should be stored under cover. Where outside storage is unavoidable drums should be laid horizontally to avoid the possible ingress of water and damage to drum markings. Products should not be stored above 60°C, or exposed to hot sun or freezing conditions.

To minimise potential incompatibilities when converting to a new grease, all previous lubricants should be removed as much as possible before operation. During initial operation, re-lubrication intervals should be monitored closely to ensure all previous lubricant is purged.
