Multifunctional sealing elements offer numerous advantages for the user. They provide ready-to-install solutions that can be assembled with minimal effort. In service applications, they help prevent counterfeit spare parts, as their typically more complex design makes them difficult to replicate. In operation, additional sealing and fastening elements can often be eliminated, resulting in more streamlined
Comparable to spring-energized U-cup seals, but without dead space. If the groove of the U-cup seal is to be avoided in applications involving paint or food products, an O-ring can be used as the energizing element instead of a spring. Particular attention must be paid to preload, elastomer quality, and Shore hardness. Due to the
This is a proven design principle in which the chemically resistant, low-friction jacket made of polytetrafluoroethylene or ultra-high-molecular-weight polyethylene is energized by a stainless steel spring. This gives the U-cup seal elasticity, provides a low initial contact force, and allows the sealing force to increase with system pressure. Low-friction designs are possible, as are applications
Memory seals are simple sealing-lip designs that offer exceptional performance at minimal cost. In terms of low friction and high sliding speeds (over 20 m/s) under completely dry-running conditions, they set the standard for applications such as dry-running compressors, vacuum pumps, and pneumatic cylinders. Cup seals (piston seals), hat seals (rod seals), and double-acting sealing
In dry-running applications, a wiper seal is required where sufficient lubrication of a rubber seal is not possible. This is the case, for example, in food and beverage processing, the painting and coating industry, pharmaceutical applications, and medical technology. We develop and manufacture wiper seals that operate entirely without lubrication and continue to function even
For use in a dry-running compressor or gas compressor, piston rings made of PTFE compounds are essential. They operate without oil, thereby preventing contamination of the gas being compressed. During the manufacturing process, they are precisely formed to match the cylinder diameter, ensuring proper contact with the cylinder wall from the outset. Due to the
Bei einem Mantelring (Rotationsgleitring, Stufenring) handelt es sich um eine einfache sehr traditionelle Bauform einer Teflondichtung, die in jedem Katalog zu finden ist. Es existieren die unterschiedlichsten Profile, im Englischen wird sie „Combined seal“ genannt. Stangen oder Kolbendichtungen werden gelegentlich auch als Wellendichtring verwendet. Meist werden sie dann für untergeordnete Aufgaben eingesetzt. Am besten funktionieren
