DBM HD DOUBLE ACTION PISTONSEAL

product

DBM KGD is a five piece double acting HD compact seal which consists of one elastomeric nitrile rubber sealing element , two polyester elastomer back-up rings on both sides to prevent extrusion into the sealing gap and two special profiled guide rings produced from thermoplastic to absorb transverse forces.

PRODUCT ADVANTAGES

  • Superior sealing performance
  • Economic sealing and guiding solution
  • For use in heavy duty applications
  • Simple groove design , one-piece piston possible
  • Long service life
  • Simple snap installation

APPLICATION
Construction machinery , fork-lift trucks , injection moulding machines , agricultural machinery , cranes and standard cylinders.

INSTALLATION
Easily assembled into one-piece piston because the back-up rings and guide rings are been produced in split forms. It is very important that the assembly tools must be of soft material and have no sharp edges. Before installation the sealing element must be oiled with system oil.

NOTES: For special applications that require high temperatures , DBM KGD piston seal is manufactured in FPM and PTFE material.

MATERIAL: POM BEARITE / TPE SEALITE / NBR 75 SH
