In fact, there're also many other uses of lubricant such as keep moving parts apart, reduce friction, transfer heat, carry away contaminants & debris, transmit power, protect against wear and to prevent corrosion. there are two main lubricants: solid lubricant and liquid libricant.Liquid lubricants can be characterized in many different ways.
