Caliber™ 3M & 5M meet the original Caterpillar "MPGM" specification. These greases contain 3% and 5% molybdenum disulfide (MoS2). Caliber 3M and 5M greases are designed primarily for use in mining equipment, such as draglines and shovels, drills, earthmoving equipment, and other heavy-duty rolling stock applications. These greases are perfect for wheel and slewing bearings, chassis points and U-joints, as well as pivot points and bucket pins. It forms a protective barrier to reduce wear and extend lubricant life, reducing parts replacement and downtime.
