3. Nothing moves without Bearings...
Bearings are the interface between rotating and stationary machine components
Bearings strongly influence the system characteristics:
Static characteristics
Rotor Dynamics
Mechanical strength
Oil requirements
Power loss
Operational safety
Gleitlagertechnik Essen GmbH

4. Lifetime of fluid film bearings: Cars: ca. 3.000 operating hours
Marine diesel: replacement after operating hours Steam turbines: ca operating hours
Hydropower turbines: > 50 years (depending on load type)

5. A strong Group for large Bearings...
More than 3500 bearings p.a.
More than 250 tons of babbitt metal p.a.
More than 140 employees
