SG Series Synthetic Grease

SG Series lubricating greases are heavy-duty multipurpose lubricating greases with development emphasis on long-term and lifetime lubrication of rolling element bearings under moderate to high load. The special lithium complex soap thickener and synthetic hydrocarbon base oil are proven components for high temperature operation. Special anti-oxidant blended additives provide oxidation stability at both low and high temperatures. Synergistic corrosion inhibitors offer protection for both ferrous and yellow metals which are commonly used in today's rolling element bearings.

Benefits

  • Made from a high viscosity synthetic hydrocarbon oil and special lithium complex soap.
  • Available in two ISO Viscosity Grades of 220 and 460.
  • Specially blended antioxidants provide oxidation stability at both low and high temperatures.
  • (EP/AW) Extreme pressure and anti-wear additives enhance the load carrying ability of the base oil.
  • Blended corrosion inhibitors protect all types of metallic surfaces including yellow metals.
  • Developed for high temperature environments.
  • Multipurpose EP grease with development emphasis on rolling element anti-friction bearings.
  • Proven operating temperature range of -30ºC(-20ºF) to 150ºC(302ºF).
  • Maximum storage period is approximately 3 years when the product is stored in the original closed container and in a dry place.

Recommended applications

Long-term and lifetime lubrication of rolling bearings in a service
temperature range between -30ºC(-20ºF) to 150ºC(302ºF).

Materials Compatibility

SG-220 and SG-460 Synthetic Grease are compatible with most seal materials, paints and plastics
