HEAVY DAS SEAL
We manufacture high quality hydraulic HEAVY DAS seals, our products are made of premium quality materials and are highly durable. We offer a wide range of sizes and also manufacture products as per our customer’s needs. DAs Seal is a double-acting seal and guide element comprising of a rubber seal, two split support rings and two split bearings, located either side of the seal. The profile seal ring seals in both the static and dynamic range whilst the backup rings prevent extrusion into the sealing gap. The function of the guide rings is to guide the piston in the cylinder tube and to absorb transverse forces. The design provides a compact seal and guide combination for a closed or split installation groove. It is a combination seals used in hydraulic applications as well as some heavy industries. The nitrile rubber seal has proved itself to be extremely wear resistant in service. It is designed to be compressed by the housing to ensure a low pressure seal and when pressurised be protected from extrusion damage by the extending lips of the support ring. A tough flexible polymer is used for the support ring which is scarf cut for assembly and to protect the seal from damage. This type is characterized by a Z-shaped back-up ring which forms a chamber with the elastomer seal ring on the inside and is centered on the outside by the guide ring. Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.
ADVANTAGES:
– Good sealing effect, also suitable for holding cylinders – Capable of installation in closed grooves for reduced machining costs – Economic sealing and guiding solution – Simple snap installation.
