Double Acting Compact Piston Seals Ring Hydraulic Cylinder Parts

DAS DAS compact seals are used as piston seals for double-acting cylinders. It has an NBR ring with 3 sealing lips in the middle; Elastomer has an good sealing effect in both dynamic and static conditions.2 polyester elastomer back up rings to reduce the allowable clearance on both sides;back up ring prevent the elastomer be extruded into the sealing gap. 2 POM ring as a guide.the role of the guide ring is to help the piston in the cylinder guide and absorb the radial force. it mainly used in hydraulic cylinders as a piston seal. As shown in the design, the sealing operation is performed by an NBR ring. Design Description: The DAS combination seal is a double-acting sealing and guiding component consisting of an elastomeric sealing ring, two backup rings, and two guide rings. The sealing ring provides excellent sealing performance in both static and dynamic conditions, while the backup rings prevent extrusion of the rubber sealing ring. The guide rings serve as effective support elements, and the unique structural design of the elastomeric component ensures distortion-free installation within the groove. The DAS seal is a compact combination of sealing and guiding, suitable for installation in open or closed grooves, enabling applications in extremely tight spaces.
