DAS/KDAS Hydraulic seals – Piston seals – Double acting compact seal

Short Description:

The DAS compact seal is a double acting seal, it is consisted from one NBR ring in the middle, two polyester elastomer back-up rings and two POM rings. The profile seal ring seals in both the static and dynamic range while the the back-up rings prevent extrusion into the sealing gap, the function of the of the guide ring is guiding the piston in the cylinder tube and absorbing the transverse forces.

product description

This kind seal are self-acting double-acting seals. The radial forces acting on the elastic rubber sealing element after installation are superimposed by the system pressure. This results in a total sealing contact force which increases as the system pressure rises. Even when no system pressure is present, good sealing is achieved. A wide mounting surface also provides additional protection against shifting or twisting of the sealing element.

The DAS compact seal is used as a sealing element for pistons and hydraulic cylinders for reciprocating motion such as earth moving machines, hydraulic excavators, cranes, forklift trucks, hydraulic tailgates, agricultural machines, etc.
