We work with design engineers in private companies, governments and associated defence sectors to formulate new synthetic lubricants that will take off with next-generation aircraft and spacecraft. Our lubricants can make that vital difference to performance, giving a device the competitive advantage that could make all the difference to mission success.
We mainly focus on two challenging categories of aerospace applications: discrete components that are lubricated for life and mechanical or electromechanical devices that must operate for extended periods in severe/harsh environments.
We split aerospace in two, that being aviation and space. Below you will see various articles covering theory, application examples and product selection guides.
Selecting the proper synthetic switch grease for a specific switch application can be a challenge. Very subtle differences in synthetic grease formulations can make a big difference and these formulation decisions are sometimes counter-intuitive. Also when selecting a switch grease, note that the viscosity of the base oil should complement…
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…
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…
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…
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 Knudsen effusion test method is used to determine the vapour pressure at several temperatures. Below is an example of how the Knudsen vapour pressure test results are displayed on a technical data sheet of one of our lubricants: As you will see, our chosen unit of measure is Torr.
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…
The grease range we offer uses a wide variety of thickener systems. The various characteristics of the thickener (also known as gellant – US terminology) gives the ability of our grease formulators to meet the challenges faced by our customers. Formulating a grease generally involves balancing the pros and cons…
Kinematic Viscosity (KV) is a type of viscosity data point that you will see on all our synthetic lubricant technical data sheets. There are different ways to measure the viscosity of a lubricant as the subject matter is not simple. Kinematic Viscosity is an oil/fluid resistance to flow under the…
Polytetrafluoroethylene (PTFE) is a fluorocarbon-based polymer which has the appearance of a white powder but the particle size varies from micron to sub-micron; final particle size depends on the milling process. The polymerisation process controls the molecular weight of PTFE and the density is approximately 2.2 g/ml. PTFE has a…
