Types of Greases

Chemtool Incorporated is a premium manufacturer of grease in the Americas.

Chemtool Incorporated offers a wide variety of lubricating greases to meet your needs. We manufacture greases that are used in a variety of markets and applications. Chemtool leads the grease manufacturing industry driven by technology, innovation and a commitment to excellence. Our customers’ challenges inspire our next products.

Grease has played an important role in our company’s past, present and future. We continue to make investments in infrastructure to improve the quality of the products we provide to our customers. While grease manufacturing facilities have closed all over the world, Chemtool has increased grease production to meet the demand. As a global grease manufacturing partner, we are positioning ourselves in line to grow the business in concert with our customers’ demands. 

Chemtool creates a variety of greases to fulfill specific on-the-job requirements:
  • Multi-Purpose
  • Synthetic
  • Chemical Resistant
  • High-Temperature
  • Anti-Seize
  • Water-Resistant
  • Food Grade
  • Heavy Duty
Advantages of Our Greases
  • Stay in place
  • Better stop-start performance
  • Sealed bearings do not require re-lubrication for an extended period
  • No need for circulation systems
  • Decrease leakage and dripping
  • Suspend solid additives
  • Provide life lubrication
  • Seal out contaminants
  • Re-lubrication while equipment is running

NOTE: Chemtool greases should be used in applications where the design does not permit lubrication by oil or the cooling function is not required and grease is the most appropriate lubricant.

GREASE SELECTION
GREASE COMPOSITION
GREASE TESTING
WHEN TO USE GREASE?
  • When oil will not stay put
  • Equipment design requires a “Solid or Semi-Solid” lubricant
HOW TO CHOOSE THE RIGHT GREASE
  • Select thickener type by application
  • Use softest consistency to stay in place
  • Select base oil viscosity as if only oil will be used
  • Determine other performance requirements AW/EP, wet conditions, tackiness, operating temperatures, etc.
GREASE CLASSIFICATION BY NLGI CONSISTENCY
