Why use an ultrafiltered lubricant in a cleanroom or vacuum environment?

Why use an ultrafiltered lubricant in a cleanroom or vacuum environment?

Sometimes it can be smaller than a grain of sand. Manufacturing equipment in Vacuum and cleanroom environments are so sensitive that even microscopic particulates can cause product failure. In a bearing, for example, any particle that acts like a ‘speed bump’ in the motion of the bearing, no matter how…

Understanding the role of antioxidants in lubricants

Understanding the role of antioxidants in lubricants

Antioxidants are additives designed to prolong the life of a lubricant by increasing the oxidative resistance of the base oil. Antioxidants allow lubricants to operate at higher temperatures than would otherwise be possible without them. Many synthetic lubricants, especially hydrocarbon-based lubricating oils, are susceptible to degradation by oxygen. This oxidation…

Lubrication regime explanation-Types of lubrication

Lubrication regime explanation-Types of lubrication

There are three primary lubrication regimes, which are boundary, mixed, and hydrodynamic lubrication. Lubrication regimes describe the type of lubrication film that is created under specific operating conditions and is dependent on the degree of contact between surfaces. Boundary Lubrication During boundary lubrication, opposing surfaces meet with little or no…

Base oil temperature capability information

Base oil temperature capability information

We have a number of base oils to select from when formulating a grease. Quite often the first way to start the product selection process is ruling out grease that doesn’t have the temperature capability that is required in your application. The chart featured on this page gives the reader…

Lubricant Additive overview

Lubricant Additive overview

There are a variety lubricant additives that we have the ability to include in our grease formulations. Note that we describe our additives, we use terminology relating to the benefit of the additive rather than than giving details of the chemical way in which the benefit is achieved; we don’t…

Pour Point test (ASTM D-97)

Pour Point test (ASTM D-97)

The purpose of the Pour Point test is to help define the lowest operating temperature for an oil. During this relatively simple test, the temperature is slowly reduced and it is noted at what point the fluid becomes too viscous to flow. Some times Pour Point is referred to as…
