Why Do Solid Film Lubricants Stand Apart From Other Lubricant Varieties In The Market?

 


Solid Film Lubricants

If you look into the various types of lubricants available in the market, one that stands out is the dry variety. They are used in situations where it is not possible to make use of liquid lubricants. Though liquid lubricants possess many qualities that are very attractive, still solid lubricants are used for many reasons. They are more certainly effective at high loads, speeds providing high stability even when there is extreme temperature, radiation and pressure. In very reactive environments, they remain the same, providing lubrication even under such tough situations.

Key Features Of Solid Film Lubricants

Some of the key points to note about solid lubricants are their thermal and oxidation stability, melting point, crystal structure, hardness etc. When it is sprayed onto a surface, it gives it protection but does not react to the material of that surface. It is best used in high temperatures that are simply not tolerated by liquid lubricants. Here is a look at the top features of solid film lubricants:

• They bring out best lubrication even when there is high humidity
• Even If the temperature is very high, their state will not change
• Using then bring out the best resistance against fretting corrosion
• Eve when there are high loads, these lubricants have c low coefficient of friction

The most important solid lubricants are Tungsten Disulfide, Graphite, Molybdenum Disulfide and much more. They can be applied as a coat on items such as automotive fasteners, spring bearings, petrochemical components, saw blades, valve components and much more.

They will not evaporate when they have to be used on a material at a particular temperature. It is to be noted that the main reason why solid film lubricants have low friction is because they come with a layering structure with weak bonds in between the layers at the molecular level. Hence each layer is able to easily slide on to another one, without the use of much force. If a solid lubricant needs to be used at very high temperature it will certainly provide satisfactory results as is seen with Molybdenum Disulfide which has the capacity to work in temperatures as high as 1100 degrees Celsius.

What Makes Spherical Plain Bearings Suitable for Most Industrial Applications?

  Spherical Plain Bearing | Img Source : blogger.googleusercontent.com Industrial applications, in which “multi-directional alignment movements” or “oscillating tilting movements are to be handled at proportionately slow sliding speeds, spherical bearings and their design variants are used. These bearing types are known to offer solutions in any operating environment. They are mechanical components crafted in different types of materials and standardized for easy interchangeability. Their distinctive features offer you a number of benefits.   Recognized for theirself-aligning characteristic, spherical plain bearings are ready-to-mount components that come in standardized sizes and dimensions for high operational reliability and easy interchangeability. With inner and outer raceways spherically shaped with ‘convex outside surface’ and ‘concave inside surface’ respectively, the bearing offers multi-directional alignment suitable to manage heavy loads at varying speeds. The bear...
