DSZ consists of a wear ring with a sealing edge and a dust-proof edge and a lip wiper consisting of an O-ring as a pretensioning element. Suitable for environments with severe or severe dust and high frequency reciprocating motion. Suitable for fast, high pressure, and necessary pressure to maintain working conditions. Recommended for double acting pistons as piston accumulators, supporting cylinders and positioning cylinders. Double safety, low friction, high elasticity, good dynamic and static sealing performance, allowing for larger extrusion clearance, while maintaining pressure and reducing hydraulic cylinder leakage. The groove is simple, the installation space is small, the sliding performance is excellent, and there is no creeping phenomenon.


Characteristics

  • Very compatible with hydraulic media.

  • Excellent sliding properties.

  • Effectively blocking the remaining oil film adhered to the surface of the piston rod from the inside.

  • Can compensate for large deformation of the piston rod or plunger.

  • No viscous and creeping when starting up.

  • Sturdy dust seal for heavy duty applications.

  • The effect of scraping off contaminants is very good, even if it is a very strong adhesive.
