Mobilgrease CM Series products are a family of extra high performance extreme-pressure greases. Mobilgrease CM-P and CM-S are NLGI Grade 2, while Mobilgrease CM-W and CM-L are NLGI Grade 1. All four products are manufactured with a proprietary high-temperature, lithium complex thickener system. They exhibit excellent resistance to softening under severe working, and provide good adhesion and cohesion. An extreme-pressure additive provides exceptional protection against wear, while additional additives enhance resistance to high-temperature oxidation and protection against rust. In addition, Mobilgrease CM-P and Mobilgrease CM-L contain 3% molybdenum disulphide for additional wear protection. Other formulation features provide low-temperature dispensing, very good resistance to water wash, and long service in bearings operating at high temperatures. These heavy-duty, severe-service greases have outstanding structural and chemical stability. Mobilgrease CM Series products won't corrode steel or copper-bearing alloys and are compatible with conventional seal materials.

 

Mobilgrease CM greases are recommended by ExxonMobil for use in for construction and mining sector applications. Mobilgrease CM-P is recommended by ExxonMobil for use in for highly loaded plain and antifriction bearings and other applications where the three percent molybdenum disulphide and high-temperature thickener system will provide extraordinary performance. Mobilgrease CM-S is recommended by ExxonMobil for use in plain and antifriction bearings in contractor and mining vehicles working under severe operating and weather conditions. The recommended application temperature range for Mobilgrease CM-P and CM-S is -20º C to +145º C Mobilgrease CM-L and CM-W are winter-grade products and are recommended for cold-temperature service. The recommended application temperature range for Mobilgrease CM-L and CM-W is -30º C to +145º C
