Mobil grease , United States

Multipurpose Synthetic Calcium Sulfonate Complex Grease

Product Description

Our Mobil SHC Centaur Series multipurpose greases are designed to provide rust protection in water-saturated environments. With a balanced combination of water washout and water spray-off resistance, as well as excellent corrosion protection, these calcium sulfonate greases are particularly well-suited for the demanding requirements of steel mill, paper machine, and mining equipment.

Mobil SHC Centaur Series multipurpose greases provide:

• Extreme-pressure protection for equipment with high/shock loads

• Low temperature pumpability

• High water washout resistance and water absorption

• High temperature bleed control
