What are Graphite Bearings?
Bearings – why it’s so important to get it right
Bearings can be made from many different metals and materials, the right bearing depends on the job at hand for the bearing, for example one bearing type is better used for high speeds and another is used for heavy loads. It is from trial and error and analyzing the errors that today we now know what materials work better in which situations to decrease the chance of a machine failing due to its bearings.
Failure caused by a bearing is very costly for an organisation, as you can imagine a whole machine breaks down which in turn will cause the product line to shut down. The machine then needs to be taken apart and analyzed as to why it is not working, and after all that time it is found that the bearing, a very small piece of metal in comparison to the whole machine, is the reason why. Failure analysis is conducted because the company will not want to simply change the bearing like for like and the machine break down in the same way a week later, again costing the company time and money.
We know of the different types of bearings such as roller bearings, thrust bearings, ball bearings, each can be made from steel, carbon steel, graphite and more. Each has its own set of advantages and disadvantages.
Graphite Bearings – what are they?
Graphite bearings are bearing in the usual manner but made from graphite rather than steel which is the more common metal. Graphite bearings have many advantages to using them compared to steel bearings for example they have self lubricating properties which for a bearing is a great commodity as obviously the more lubricated the bearing the less friction there is and the faster the bearing can move. Graphite bearings are commonly used when the temperature of the bearing is very high, and they can be exposed to a wide number of chemicals without corroding.
As well as these strengths graphite bearings can be impregnated with resins and other materials to enhance their qualities to handle even high temperatures and oxidation resistance, a little like giving an engine a turbo boost.
