For a piston rod in a refrigeration compressor, it was necessary to absorb both the vibrations and lateral misalignment of the plunger. In addition, the guide system had to provide a long service life and be chemically resistant to the refrigerant.The solution consisted of an aluminum flange into which spring-elastic U-cup seals were press-fitted. Their

For beverage filling applications, gas control valves are used and must be positioned close to the actual filling valve. A previously common valve design was oversized and incorporated a space-consuming bellows seal. We succeeded in retrofitting the existing valve with a PTFE diaphragm without reducing the valve stroke (plexiglass model).The NBR actuator diaphragm was replaced

For a CNC ceramic grinding machine used in medical technology, a multifunctional wiper assembly incorporating two U-cup seals was required. The customer supplies complete ceramic solutions for dental restorations (crowns, bridges, and implants). Following nearly 20 years of cooperation, we were entrusted with the further development of an existing design. Whereas the previous generation featured
