From failure analysis to standardized test orders – we offer the complete spectrum of sealing technology services.
Sealing problems are often complex and multifactorial. Root causes may lie in the material, geometry, surface finish, lubricant or operating conditions.
We systematically analyze your specific sealing problem and develop practical solutions together with you, drawing on the close collaboration with the Institute of Machine Components at the University of Stuttgart.
Lead measurement on a seal counter surface
Three-dimensional capture of the shaft surface using optical measurement technology. Visualization of roughness and lead.
Quantitative detection and evaluation of micro lead and macro lead on the counter surface – decisive for the sealing performance of radial shaft seals.
Determination of the radial force of radial shaft seals.
3D representation of a macro lead on the shaft surface
3D topography of a ground shaft
On our test rigs we conduct lifetime and functional tests on radial shaft seals. Test conditions (speed, temperature, medium) are adapted to your requirements.
Our test rig capacity covers shaft diameters from small to large sizes and allows the parallel testing of multiple seals under identical conditions.
Seal test rig with drive unit and instrumentation
The compatibility of the lubricant with the elastomer material of the seal is a fundamental requirement. We conduct standardized elastomer–oil compatibility tests:
Standardized test for assessing the oil compatibility of elastomer seals in Flender gearbox applications.
Testing according to SEW standard for approval of gear oils in combination with radial shaft seals.
Test rigs for standardized oil compatibility tests
