Hydraulic DAS/KDAS Piston Seal PU seals piston rod seal shaft seal

KDAS Piston Seal, the combination seal ring is a double acting piston seal ring, two retainers, and two wear-resistant rings. There is a real sealing element in the middle; There are setting a retaining ring and a wear-resistant ring on each side. Besides, the retaining ring prevents the sealing ring from being squeezed into the clearance. The sealing ring in the middle is a dentate sealing ring, which can play a good role in static and movement. In addition, the wear ring ACTS as a guide to the piston in the cylinder and bears the radial force.
