Existing seals
Replace without changing the housing
When an existing sealing point causes trouble, the design does not have to change straight away. These five designs reproduce common geometries to DIN 3760 — and thanks to the low contact pressure they often need no reworking of the shaft.

The limits for pressure and circumferential speed apply separately, not simultaneously. The temperature range depends on the elastomer selected.
Why a straight replacement is often enough
No reworking of the shaft
The VR sealing lip works with a much lower contact pressure than a conventional shaft seal. That has a practical consequence: post-treatment of the shaft can usually be dispensed with — no hardening, no nitriding, no hard chrome plating, no liner. It also seals reliably on unhardened and on stainless steel shafts, and it leaves no running-in mark.
Applies under appropriate operating conditions. For higher pressures, higher circumferential speeds or abrasive media, please talk to us.
- The existing installation space stays as it is
- Shafts that have already run in can usually still be used
- Lower friction power reduces the temperature at the sealing point
- Longer maintenance intervals
