Requirements:
Sealing systems for use in wind turbines and injection molding machines have to meet exacting demands in terms of friction behavior and system availability. Long, maintenance-free operating intervals must be achieved. In some cases, system life should be as much as 20 years.

Typical requirements:
Operating temperature: -40 °C to +100 °C
Operating pressure: ≤250 bar
Special operating conditions:
   – Extremely high system availability required
