Different Types of Lubricants

The most frequent use of a lubricant is to eliminate interference between two surfaces, although each lubricant is unique.


Because they are regarded as novice personnel or apprentices, lubrication systems are routinely allocated to new employees. Understanding the different lubricants is helpful. This guarantees the wrong type is never used in the incorrect application. This will decrease machine downtime and failure.


  • Oil
  • Grease
  • Penetrating Lubricants, 
  • Dry Lubricants. 


Greases


Grease is made by blending oil with thickeners (such as lithium-based soap). Lubricants like molybdenum disulphide and graphite, among others, maybe mixed with other particles.

Greases combine well with the lubricants in the oil, providing stickiness and enabling the fats to concentrate on the surfaces. Grease may also operate as a barrier, shielding surfaces from pollutants that might cause harm.

Several greases and oils, for example, were available in a range of viscosities. Grease is a disadvantage in fast-running equipment because of its excessive thickness and sticky nature, readily producing resistance.


Oils


These liquids are made up of long polymer chains with additional ingredients. They are difficult to squeeze out between the surfaces of the lengthy chains, but with the application of oil, you may create a slick barrier. Oils vary in their viscosity. Lower numbers indicate a more effortless flow.

  • It is used to manufacture bearings, hinges, blade sharpening, and tool maintenance.
  • Essentially, oil is used to lubricate everything that does not need grease usage if you need to lubricate the miniature components without disrupting anything else.


Lubricants for Penetration


You will understand why these oils require their section if you are a shade-tree technician. On the other hand, these coated components and lubrication systems are not designed for long-term lubrication. Because of their low viscosity, these oils are specifically designed for one purpose: to enter the microscopic crevices on the surfaces, promote lubrication, and break apart the rust. There are many different penetrating oils, but you must know how to manufacture low-cost penetrating oils.

A dry lubricant is a perfect option when you cannot use oil or grease because they collect dust and dirt. The tiny particles that make up dry lubricants (like graphite) are very slippery at the molecular level. Dry oil is often in the form of a spray that has been blended with water, alcohol, or another solvent that will ultimately evaporate, leaving behind a thin coating of lubrication to minimise friction.


When Is It Appropriate to Use Dry Lubricant?


  • Locks, hinges, and threaded rods
  • Small components that cannot be blocked with oil or surfaces that must be kept clean
  • It is not advisable to use a lubricant that collects dust or dirt.
  • Extremely high temperatures or pressures may be applied to surfaces. If this happens, oils will begin to oxidise.
