Mobilgrease CM-S (5 Gal. Pail)

Mobil 101922

Mobilgrease CM-S is an NLGI Grade 2 extra high performance extreme-pressure grease. It is formulated with a proprietary lithium complex thickener system that provides excellent protection in high temperatures. It also contains an extreme pressure additive for exceptional wear protection under severe conditions, as well as other additives for high-temperature oxidation resistance and rust protection. Mobilgrease CM-S remains in place, exhibiting resistance to water wash and high temperatures, and won't corrode steel or copper-bearing alloys. It is also compatible with conventional seal materials.

Mobilgrease CM-S is recommended for use in contractor or mining applications for plain and antifriction bearings working in severe operating and weather conditions.

Product Data Sheet

Mobilgrease CM Series greases are leading members of the Mobilgrease brand of products, which has gained a world-wide reputation for innovation and performance excellence. Mobilgrease CM Series grease products are designed by our formulation technologists and backed by our world-wide technical support staff.

Mobilgrease CM Series greases are designed specifically to meet the needs of customers with heavily loaded equipment that require high EP/antiwear performance which remain in place even in tough conditions of water wash, high sliding and high temperature. These greases are targeted especially for the severe construction and mining sector and offer the following features and potential benefits:

Features Advantages and Potential Benefits
Excellent resistance to water, including spray Maintains excellent lubrication properties and protects equipment in conditions of water contamination
Very good EP and anti-wear protection Lower maintenance costs and less unanticipated downtime
Better stay-put properties at high temperatures Excellent performance in high shear, high load applications, especially where grease re-supply is limited
Resists rust and corrosion Protects equipment in presence of water for reduced maintenance and longer equipment life
Good pumpability at low temperatures Excellent low temperature properties including start-up in remote locations

Recommended by ExxonMobil for use in:

Heavily loaded applications or environments highly contaminated with water, especially in the contractor / mining sector. Specific examples of such applications include:

  • Heavy-duty trucks especially, hinge and bucket pins
  • Mining and construction equipment
