Types of Lubricants

• The lubricants are the different types of oils used for lubrication. Lubricants are obtained from animal fat, vegetables and minerals. The lubricants made of animal fat does not withstand much heat, it becomes gummy and waxy and hence not suitable for machines. Vegetable lubricants are obtained from seeds and plants such as cotton seed, olive oil, linseed oil and castor oil are used as lubricant in small machines. Mineral lubricants are most popular for engines and machines. It is obtained from crude petroleum, which is a natural resource. Mineral lubricants are less expensive and very much suited for internal combustion engine. Now days synthetic oil, which are produced from sand and coal such as poly alkaline and glycol are also used as lubricants.
• There are different types of lubricants such as Solid lubricants (Graphite, Mica, Talc powder), Liquid lubricants (animal fat oil, vegetable oil, mineral oil) and Semi solid (Grease)
