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…
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…
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…
Polyglycol or Polyalkylene Glycols (PAG) are a family of products formed from the polymerisation of one of more alkylene oxides. PAGs are made from ethylene oxides, propylene oxides, which in the presence of an alcohol initiator and a catalyst form a long chain polymer. Other names you may come across…
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…
The Silicone oil family is a group of synthetic polymers that combine an inorganic silicon-oxygen backbone with organic side chains, which can include methyl, phenyl and trifluoropropyl. Variations on the chemical structure affect the properties. Silicones are also called Polysiloxanes. Poly(dimethylsiloxane) are the most common silicone used commercially. PAO summary:…
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…
Polyphenylethers (PPE) are long chain aromatic ethers that consist of benzene rings (phenyl groups) joined by oxygen atoms. PPEs are ideal for radiation resistant applications, used for example in nuclear power plants and MRI scanners. Polyphenylether summary: Keep in mind that if a Polyphenylether is used as the base oil…
