The seals used in plant engineering must have a very long service life. Once they are installed — to protect offshore wind turbine towers from salt corrosion, for example — customers (typically) require that they perform perfectly for more than 20 years. The service life of a seal is limited on the one hand by setting or stretching (physical … [Read more...]

FKM special compound seal for use at high temperatures
COG’s new high performance material Vi 250 seals air at temperatures of up to 250 °C, even over the long term. Furthermore, the all-round compound also impresses thanks to its excellent media resistance, and is also resistant to chemicals such as for example all types of hydrocarbons. FKM possesses extraordinarily good resistance to numerous … [Read more...]
New rotary shaft seal coating reduces wear and shaft runout
The optimum function of rotary shaft seals depends on many factors. One of them is the wettability of the sealing lip. This parameter plays a particularly important role with synthetic lubricants such as polyglycol. If wetting is too low, not only does wear on the sealing lip increase, but the contact with the rotating shaft can also damage the … [Read more...]
Wedge-shaped seal for shock absorbers simplifies installation, reduces friction
Shock absorbers ensure that a car’s wheels stay on the road, making them a key safety element in any model. A new design concept from Freudenberg Sealing Technologies simplifies the installation of the seal between the housing and the piston rod inside the absorber. The wedge-shaped seal also reduces friction, leading to less wear. If a vehicle … [Read more...]
