The support rings B position the elastic element and prevent radial gaps, with protrusions to prevent rotation.
The guide rings C provide guidance and absorb axial forces, allowing pressure oil to flow through to maintain pressure balance and prevent excessive pressure buildup in front of A.
The hardness of the seal material increases from the inside out, and the DAS seal is a self-tightening, double-acting seal that maintains its sealing effect even without system pressure.
Core Feature
