Industrial lubricants are basically defined as compounds like fluids, greases and oils. They are used in order to lessen wear and tear of materials while reducing binding and friction. In some extreme cases, they may also prevent or lessen electrical resistivity while it increases thermal conduction. Of course, they are also favored because they can prevent corrosion in both the inner and outer surfaces where they are applied.There are various types of industrial lubricants including low and high viscosity oils, lubricant powders, waxes and high temperature silicates. With lubricating oils, other forms are also seen such as natural and synthetic oils. At times, they may also be combined with waxes or dispersions of solid lubricants. There are still other forms of lubricants used in several industries.
METAL WORKING FLUIDS
As the name suggest helps in changing the shape of metals in which it is worked on. There are Two sub categories of these lubricants as per there working application. Firstly it is metal working by abrasion and removal by cutting the example being Honning, Grinding, turning, milling etc. and Secondly it is by deformation like drawing,bending rolling etc.
INDUSTRIAL GEAR OILS
Most of the industrial gear boxes are big unit of combination of single type or mixed different types of gears.They may be used to increase or reduce the speed transmission of load or change of direction of load.They work in extreme work environment and in varying load and temperature ranges and conditions . The working of gears, the gear types, temperature ranges and the load factor and even the gear metallurgy requires varying type of base oils and additive chemistry.
HYDRAULIC OIL AND TRANSMISSION FLUIDS
With the name alone, one will be able to say that these lubricants are made specifically for power transmission and hydraulic equipment. Power is transmitted from the fluid through the aid of hydraulic lines before they are transferred to a cylinder. Transmission fluids on the other hand are useful in applications like gearbox assemblies. Most hydraulic and transmission fluids include synthetic lubricants, oil-water emulsions and petroleum or mineral oils. They are specifically used in aerospace, automotive, military and marine applications.
HEAT TRANSFER FLUIDS AND THERMAL OILS
These are forms of industrial lubricants utilized in order to carry thermal energy for various applications such as metal working, machine cooling and process heating. It includes other products to provide machine cooling such as chiller fluids, refrigerants and circulating coolants. For heating purposes, products such as hot or heater oils are found.
There are still other types of industrial lubricants. Industrial greases form part of this industrial product category. This type of grease is like a thickened gel that may either come from semi-synthetic, synthetic or natural substances.Greases, gels, and lubricating pastes are thick, high viscosity products that do not run or flow off surfaces. Micro-dispersions are oils or lubricating fluids that contain a dispersion of solid lubricant particles such as polytetrafluoroethylene (PTFE), graphite, and molybdenum disulfide or boron nitride (BN) in a mineral, petroleum or synthetic oil base. Fluid lubricants are a broad category that includes coolants, refrigerants, base oils, and transformer oils. Solid lubricants or dry film lubricants are compounds such as hexagonal flake graphite that are designed to reduce friction, binding or wear; exclude water; or provide other specialized characteristics.
