zurcon® rimseal
The Zurcon® Rimseal was developed as the secondary seal in this system to ensure reliable sealing of thin oil films at low secondary pressures
Commercial Description
The Zurcon® Rimseal was developed as the secondary seal in this system to ensure reliable sealing of thin oil films at low secondary pressures. A Zurcon® material (polyurethane Shore D 58) is used combined with a new seal profile. The contact pressure curve is automatically optimized under dynamic conditions. The final outer element of the redundant sealing system is a double-acting scraper seal (e.g. DA24, DA 22, Turcon® Excluder® 2). The optimum sealing system thus consists of three independent lip seals installed in line, whereby the hardness of the material decreases from the pressure side to the atmospheric side
When the field of application and system requirements make high demands on leakage control and operational reliability, a redundant sealing system is necessary to ensure reliable sealing of hydraulic cylinders at the piston rod. Sealing systems with elastomer-energized polymer seals are a proven answer to widely varying demands for standardized grooves, simple installation, resistance to media, high and low temperatures and pressures.
The system offers enormous flexibility in the choice and matching of materials. The piston rod sealing system for hydraulic cylinders subject to heavy loads should consist of three elements: The Turcon® Stepseal® 2K or V used as primary seal. This seal element offers the back pumping property necessary for redundant rod seal systems as well as good resistance to high and low temperatures and high media resistance.
