Across various industries, there is a whole range of different lubricants, oils and greases that help to keep the various machines, engines, vehicles and more running at peak performance.

These primarily include enhancing the existing desirable properties, suppressing the existing undesirable properties, and imparting new properties. The NLGI has established consistency numbers or grade numbers, ranging from 000 to 6, corresponding to specified ranges of penetration numbers.Soaps are the most common emulsifying agent used, and the selection of the type of soap is determined by the application. A common feature of greases is that they possess high initial viscosities, which upon the application of shear, drop to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. Even if two paint colours look the same, car manufacturers make loads of different exterior paint colours and they can all vary from year to year, so you need to make sure the code is right to get an exact paint match. Lubrication controls friction and wear by introducing a friction-reducing film between moving surfaces, so a lubricant such as grease helps reduce friction in two ways. For example, if you work in a high-pressure environment, more of your lubrication needs would be met with a heavy-duty grease.

Fresh and salt water affects normal types of grease, so marine grease has been designed to withstand water. Lol, ben non, c'était le tube de graisse que j'attendais pour pouvoir effectuer le remontage d'un engrenage plastique neuf sur un drone qui avait besoin d'une réparation à ce niveau. It also features friction-reducing solid lubricants to provide sliding surfaces with additional protection, all while being easy to apply with a grease pump or gun, paddle, or brush and suitable for use in operating temperatures ranging from -20°C to +130°C. The dropping point indicates the upper temperature limit at which a grease retains its structure, not the maximum temperature at which a grease may be used. The main elements of standard ATSM D4950 and NLGI's consistency classification are reproduced and described in standard SAE J310 “automotive lubricating greases” published by SAE International.Components inside machines come into contact with each other when they are in operation, generating friction and heat. The consistency of the grease means that some pressure must be exerted to force it to flow; for this we use grease pumps. Both automatic grease traps and GRUs are important for businesses because they help to reduce the amount of grease and oil that enters the sewer system.

This is designed not to drip or disperse and also acts as a seal to prevent contaminants from entering. Industrial grease reduces and minimizes these effects and increases the service life of the machinery. To measure penetration, a cone of given weight is allowed to sink into a grease for five seconds at a standard temperature of 25°C (77°F). Our universal greases are for a wide range of lubrication applications in machines and moving machine components, such as bearings, (open) gearboxes, chains, runners, fans, axles and more. Consequently, without the ability to transfer away heat, excessive temperatures result in accelerated oxidation or even carbonization where grease hardens or forms a crust.Cette graisse au lithium est réputée pour ne pas attirer la poussière, et elle est compatible avec les engrenages réducteurs en plastique et autres matériaux high tech . Our 20 years of experience are invaluable when it comes to choosing the right maintenance methods for your industry and the environment your machines operate in. EP greases have increased resistance to film breakdown, form sacrificial coatings on the metal surface to protect if the film does break down, or include solid lubricants such as graphite or molybdenum disulfide to provide protection even without any grease remaining. Nonsoap thickeners are also gaining popularity in special applications such as high-temperature environments. E. and anti-corrosion agents, designed for use in all anti-friction and plain bearings subjected to high load, and where water washout or ingress is a problem.

Boats and boat trailers also require the use of grease, however it needs to be suitable for high exposure to water. It’s not simply the case that one is any better than the other, but more a case that one is better suited to the job in hand. Consistency of a grease may change as it’s worked or sheared – so its ability to maintain its consistency when worked it its shear stability.For tips on how to use your lubricants properly, read our eight rules to lubrication management, or speak to a member of the Crown Oil team today.
