Castrol Tribol™GR SW 460-1

Description

Castrol TribolTM GR SW 460-1 is a lithium complex based grease containing a synthetic base fluid working in combination with Castrol’s unique MicroFlux Trans – Plastic Deformation (MFT-PD) additive technology. The waxfree nature of the synthetic base oil and the low coefficient of friction provide excellent low temperature pumpability as well as very low starting and running torque. It can also offer the potential for energy savings and can reduce operating temperatures in the load zone of rolling and sliding element bearings. The lithium complex thickener gives excellent adhesion, structural stability, sealing effects and water resistance. Primarily intended for a wide variety of applications at extremes of temperature, the grease also has a high level of chemical stability and provides excellent protection against wear, rust and corrosion. The MFT -PD additive technology provides unsurpassed wear protection and an extremely low coefficient of friction even under extremes of pressure, vibration, shock loads, at high or low speeds. Under severe load, components of the MFT-PD additive combination are activated, initiating an improvement of surface friction characteristics through plastic deformation. Unlike the case with conventional lubricants, the layer formed by MFT-PD provides excellent lubricity and adhesion. 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

Tribol GR SW 460-1 is recommended for tough industrial applications especially as encountered in Wind Turbine Main Bearings, Pitch and Yaw Bearings It gives outstanding bearing protection under high loads at low to moderate speeds and in applications where water resistance is critical. A very important feature is to help to reduce wear from static vibration known as false brinelling and from sliding motion due to axial thrust. These are the most prominent failure modes in Wind Turbine main bearings.
