Answer:
The difference between greases and pastes is that, among other things, pastes contain more solid lubricants than greases do. A lubricating paste is categorised by the fact that it contains more than 10% solid lubricants, a grease contains less than 10%. This often determines the consistency of the lubricating paste - it will be firmer than a grease usually is - but not always.
Properties and uses of greases and pastes
Lubricating pastes are often ideal for plain bearings and applications with slow or vibrating movements, as well as high temperatures and loads. Grease is a lubricant whose properties depend entirely on its composition, so it is important to have a clear specification of requirements for your intended grease.
