Hydraulic cylinder, pressure of liquid extrusion sealing pressure type rubber u channel seal, make further deformation, and on the sealing surface of the larger with the pressure of the liquid pressure, strictly speaking should be pressure. Higher and higher additional contact stress and contact with initial stress together to prevent leakage of liquid pressure. But when work pressure is greater than 10 mpa, in order to avoid quality synthetic rubber sealing part of the compression type rubber u channel seal are in seal gap in cut off in the hydraulic cylinder reciproing motion caused by leakage, must be in synthetic rubber sealing quality compression type rubber u channel seal of the pressure side each set a synthetic resin retainer, such as nylon retainer, polyformaldehyde collar and filled ptfe ring.

The dust ring can be used for two purposes according to the material. The dust ring with the skeleton is generally used under the work of bad environment. The commonly used dust ring is made of polyurethane material. Different material combination sealing effect will gradually improve, the use of engineering conditions will also improve. Most appliions are in the low friction and low resistance range, and fast running speed of the hydraulic cylinder.
