Development and qualification of resource-efficient slide bearings technology for fluid-lubricated systems in pumps

In chemical and plant technology (power stations, industry, buildings) pumps which contain fluid-lubricated, slide bearings and mechanical seals are often used. Typical bearing materials used are wolfram, cobalt and nickel; however, only limited quantities of these raw materials are still available (W, Co), or they are considered a health hazard (Ni). In addition, wear and tear and corrosion on these bearings cause considerable damage to machines.

Thus the main aim of the project is the development and qualification of an innovative slide bearings system for fluid-lubricated applications. The standard bearings material should be replaced with a ceramic material.
