Features & Benefits
• Heavy-duty grease that does not contain any metallic soaps and exhibits outstanding Oxidation and non-ageing characteristics.
• based on polyurea thickener which offers excellent shear stability for long life under arduous working conditions including high and shock loads as well as high temperatures
• shows steady consistency with temperature changes and is ideally suited for high duty wide temperature applications.
• Highly effective control over rust, corrosion and oxidation.
• shows good water washout and water resisting properties and can safely use in applications where water ingress in encountered.
• excellent sealing properties, facilitating extension of relubrication interval.
Applications
MAGNA™ PolyGuard Ultra GREASE is a multifunctional product suitable for a wide range of applications, providing long-life lubrication of bearings and mechanisms. It is especially recommended for heavy-duty steel plant applications where the combined effects of high temperature, heavy load, and water ingress are encountered.
MAGNA™ PolyGuard Ultra GREASE can be applied manually, with a standard grease gun, or through centralized lubrication systems. As with all greases used for the first time, it is essential to thoroughly clean and purge bearings of any previously used grease before application. Care should be taken to avoid over-lubrication and to apply only the quantity of grease recommended by the bearing manufacturer.
