Mapro LGHB 2/5 High Load, High Temperature, High Viscosity Bearing Grease

A high viscosity, mineral oil based grease, using the latest complex calcium-sulphonate soap technology. Formulated to withstand high temperatures and extreme loads, it is suitable for a wide range of applications, especially in cement, mining and metal segments. This grease contains no additives and the extreme pressure properties arise from the soap structure.

• Excellent load capacity, anti-oxidation and corrosion protection even with large water ingress
• Withstands high peak temperatures
