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…
A common question from engineers is a concern that an electrical connector grease that contains sulfur will interact with terminal metal plating materials, which could be a risk to continuity. The short answer is yes, our connector greases contain inactive sulfur. But there is a difference between inactive and active…
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…
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…
Grease does not attract dirt. Grease is not polarised and does not act like a magnet for dirt. Sure, if dirt lands on top of grease it will stick there, but that’s one of the reasons for using a connector grease, as a protective barrier……the grease will protect the contact…
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…
Petroleum or mineral oil based grease is the most common and lowest cost grease on the market. If you have a lubrication task and are considering a grease, a grease that uses a mineral oil should be considered. Why? Well why should you pay for characteristics and features that you…
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…
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…
We use two types of silica as a thickener in our grease range, both fumed silica and hydrophobic silica. Silica is not to be confused with silicon or silicone. Fumed silica is hydrophilic (water-loving) and has a thixotropic behaviour due to it’s time dependent recovery of apparent viscosity after shear…
