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…
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…
A manufacturer of diamond cutting tools for ultra-precision and optical manufacturing applications was having lubrication issues with leads screws in their custom-built cutting machines. The screw drive system controls the device table so a smooth movement is crucial. The competitor grease was not performing well, there was a ‘stick-slip’ issue…
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…
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…
Alkylated Naphthalenes (AN) are a reaction of olefins with a naphthalene nucleus resulting in a base oil with excellent thermal and oxidative stability. In addition AN has first-rate hydrolytic stability and is miscible with other synthetic hydrocarbons, most notably Polyalphaolefins (PAO). Alkylated Naphthalenes summary: Keep in mind that if a Alkylated…
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…
If you are trialling the use of a grease or oil in a prototype device then you will appreciate how crucial lubricants can be; extending the functional life of components, improving the tactile feel of customer operated controls…the reasons to include a lubricant are many and well worthwhile. Before you…
Polyalphaolefin (PAO) oils are stable, lubricious fluids that are compatible with most plastics and elastomers. PAO oils are considered a great replacement for petroleum based products, are used in countless applications and industry sectors. PAO summary: Temperature range of -60 to 125°C Relatively low cost Excellent wear reduction Good plastic/elastomer…
