Specification
 

 
 
Excavator Seal Kit Describe
 

Piston seal maintain sealing contact in sliding motion between the piston and cylinder bore. Differential pressures acting on the piston to extend or retract the piston rod can be in excess of 400 bar (5,800 psi). The pressure acting on the piston seal increases contact forces between the piston and cylinder surface. Therefore the surface properties of the sealing surfaces are critical to proper seal performance.
Piston seals are typically classified into single acting (pressure acting on one side only) and double acting (pressure acting on either side) seals.
Costumer Hydraulic Cylinder Piston Seal SPGW with Factory Price
SPGW PTFE bronze hydraulic compact seal is a four piece double acting heavy duty compact seal which consist of one PTFE bronze profile ring,one elastomeric nitrite rubber pre-load sealing element and two thermoplastic back-up rings.
Product Advantages of SPGW piston seal:

1. High sliding speed
2. Low friction,free of stick-slip
3. Simple groove design
4. Long service life
5. Very good sealing performance even with pressure speaks
6. High resistance to abrasion
7. Increase clearance possible
 

Features
 
SPGW is double acting hydraulic piston seal. It is a combination of a slipper seal and an energizing square ring.
Advantages:
High static and dynamic sealing effect;
High resistance against extrusion;
Low friction,high efficiency;
Stick-slip free starting,no sticking;
High abrasion resistance,high operational reliability;
Wide range of application temperatures and high resistance to chemicals,depending on the choice of square ring Material.
Application Range:
Standard compact seal for wide application. Design and apply please referring to NOK's SPG series standard.
Characterisstics:
A combination of a based material slipper seal of PTFE with law coefficient of friction, no stick-slip behavior and high wear
resistance. Double sealing performance saves installation space.
