Oil based lubricants are used for a whole range of applications, helping to minimize friction between moving parts and maintain mechanical efficiency. An oil-based protective film can also work to absorb friction-generated heat and act as a coolant. Oil-based lubricants are available in different viscosities, with lower weight numbers indicating a thinner product.
Grease-based lubricants are tough and long-lasting, making them ideal for industrial applications. Synthetic grease is often preferred over petroleum-based grease for heavy-duty equipment. This included gears, bearings, axies and other machinery that operates at high temperatures, torque and shear stress.
Penetrating lubricants aren't designed for long-term use but can be extremely useful when dealing with rust, debris and other contaminants. these low viscosity fluids infiltrate minute cracks and provide lubrication where other products fail. WD-40 is one of the most widely used penetrating lubricants and is a mainstay in garages around the world. Oil refineries, drilling rigs, industrial factories and other heavy-duty operators tend to rely on more specialized products.
When oil and grease-based products aren't an option, dry lubricants step up. make up of tiny particles, dry lubricants are slick and smooth, without an oily residue. Often manufactured with graphite and molybdenum disulfide, dry lubricants are usually blended with a solvent such as water or alcohol. they're sprayed onto a surface, where the solvent evaporates and leaves behind an ultra-thin layer of dry lubricant.
