KDAS combined seal ring is a two-way acting piston seal ring, the combined seal ring is composed ofan elastic rubber ring, two additional retaining rings and two wear rings. The desian provides a compactcombination of seal and guide, and is suitable for mounting the combined seal ring in the closed groove.The combined seal ring comprises an elastic toothed seal ring, two retaining rings and two weal rings.There is a real sealing element in the middle; And place a block ring and a wear-resisting ring on eachside. The retaining ring prevents the sealing ring from being extruded into the gap; The middle sealingring is a tooth sealing ring, at rest and movement can play a good sealing role. The role of the wear ring isto guide the piston in the cylinder block and to withstand radial force.
KDAs combined oil seal material:
1, toothed sealing ring: nitrile rubber (NBR);
2, stop ring: containing additives green blue polyurethane elastomer
3,wear ring: glass fiber reinforced thermoplastic polymer.
KDAs combined oil seal advantages:
1, closed groove and integral piston
2, the total length of the piston is short;
3.the sealing ring and wear ring share a groove,
4. Low production cost of piston;
5,sealing ring and wear ring cheap;
6.Strong extrusion resistance to clearance;
7, the elastic sealing ring will not twist and turn;
8, good leakage performance;
9. The retaining ring and wear-resisting ring of oblique incision are easy to assemble
KDAs combined oil seal application range:
KDAS combined seal rinas are often used as sealing elements in reciprocating hydraulic cylinders andpistons, such as light bulldozers, injection molding machines, bottle blowing machines, cranes, forklifts
