The disk stabilizes and centers the seal on the shaft and provides improved adjustment behavior under various load situations, thus ensuring consistently precise performance.

PTFE (polytetrafluoroethylene) is characterized by extraordinary chemical and thermal resis-tance. It also has the lowest friction coefficient of all solids. Due to its extremely low surface tension, there are virtually no materials that adhere to PTFE.

PEEK (polyetheretherketone) shows a resistance to chemicals and high temperatures compa-rable to PTFE. In addition, PEEK excels through its mechanical strength and stability which is higher than those of most thermoplastics.

The result of this innovation: excellent wear and sliding behavior, consistently precise perfor-mance, robustness or minimum wear and - not least due to the self-cleaning surface - reliable use in various application areas.
