Lubricating grease vs lubricating paste

Lubricating grease and lubricating paste are both means to lubricate an application that needs a firmer type of lubricant than a lubricating oil can deliver. The difference between grease and paste is mainly that grease contains about 3-4% of solid lubricants, while paste contains up to about 50% of solid lubricants. Lubricating pastes are therefore usually a thicker type of lubricant, with extra good adhesion. 

Properties of lubricating pastes

Lubricating pastes are generally particularly useful for high loads, temperatures, plain bearings and applications with vibrating or slow movements. Metal-free lubricating pastes (for example OKS 250) and OKS 252 can also be used for corrosion protection of screws, and for bolted joints. A lubricating paste consists of one or more base greases/base oils, and various types of solid lubricants. The solid lubricants can act as thickeners, but their main function is to give the lubricating paste properties that a grease/lubricating oil does not have. 

Properties of grease

Grease is an excellent lubricant when you need more effective adhesion than a lubricating oil can deliver. Greases contain a base oil, as well as thickeners and various additives. The mixture and quantity of these respective components determines the properties of the grease. As a rule, there is no lubricating grease mixture that works optimally for all applications, but you should always choose the grease based on an established specification of requirements and the type of application/machine to be lubricated.
