Products Description
The hydraulic double acting compact seal is a seal for hydraulic cylinder pistons. This seal usually consists of an elastomeric sealing ring, two anti-extrusion rings, and two guide rings. The elastomeric sealing ring provides good sealing in both static and dynamic ranges.
Advantages of Hydraulic Double Acting Compact Seal
1. Good sealing effect, also suitable for holding cylinders.
2. Insensibility against shock loads and pressure peaks.
3. High resistance against extrusion.
4. Economic.
5. Easy installation.
Structural design
Compact Seal is a double-acting seal and guiding element comprising an elastomeric profile seal ring, two back-up rings, and two guide rings.
The profile seal ring seals in the static and dynamic range with backup rings to prevent extrusion into the sealing gap. The middle of the sealing ring plays a good static and dynamic sealing role. In addition, the two guide rings act as the guide element of the piston in the cylinder and bear the radial force.
