Product Description

Mallos OGWR 80 is a premium lithium soap thickened Open Gear grease formulated with advanced extreme pressure (EP) and anti-wear (AW) additive technology. It contains specially selected polymers to provide extra adhesive strength and water resistance in the harshest climatic conditions found in mining and other industries.

Mallos OGWR 80 is a special grease developed primarily for Open Gear type equipment but also suitable for wire rope and other similar mining and industrial applications. In addition to its EP and anti-wear characteristics it also provides a high level of oxidation, rust and water washout protection. The presence of Molybdenum Disulphide (Moly) at 2.5 wt% further strengthens its wear properties particularly for sliding and shock load conditions.

Mallos OGWR 80 has demonstrated outstanding performance with regard corrosion protection, low temperature pumpability and high temperature service. Most importantly, Mallos OGWR 80 possesses special adhesive components to resist throw-off and maintain a tenacious lubricant coverage to protect gear teeth and other metal parts.

The state-of-the-art equipment and procedures employed to manufacture Mallos OGWR 80 provide it with a high degree of mechanical and storage stability. It will not breakdown under high mechanical stress. In storage it will not alter consistency or release oil.


Mallos OGWR 80 is particularly recommended for use on open gearing found in the mining, sugar & general industry. Some examples are kilns, grinding mills, draglines and shovels. It also functions as a multi-purpose mining lubricant and suitable for various wire rope and other applications where contamination with dirt and water are a concern.

The recommended operating temperature range is from –20°C to 140°C however Mallos OGWR 80 can endure higher temperatures for short periods or if the lubrication frequency is increased.
