We have been manufacturing and developing dynamic shaft seals for over 60 years. Whether micro lips, F-LESS® or PTFE - all variants can be combined with a wide range of designs and are easy to install.

Integrated dynamic shaft seal systems at a glance:

• Wide range of materials: ACM, FKM, HNBR, PTFE
• Designs:
  • Radial rotary shaft seals (RWDR)
  • (Semi) cassettes
  • Integrated RWDR in modules (IWDR®)
  • Integrated RWDR in modules with speed detection (IWDS®)

• Features:
  • Space-optimized design
  • Contacting or non-contacting radial protective lip(s)
  • High speed resistance
  • Axial protective lip(s)
  • Half-shoulder RWDR/full rubberized RWDR
  • Aluminum reinforcement plate for weight reduction
  • Noise decoupling through SEM tracks

Our F-LESS® technology, introduced in 2004, was developed to meet the high demands of modern engine technology and surpasses all elastomer and PTFE shaft seals in terms of durability and reliability. The combination of flat sealing lip contact and the ease of installation of a springless elastomer rotary shaft seal makes it extremely robust and cost-effective to install. In addition, F-LESS® offers ideal testing possibilities thanks to optimum air leakage values.
