K38 is a single acting rod seal with symetrical lips and an additional sealing lip which improves the leakage behaviour and at the same time, prevents the entry of dirt from the wiper side.

PRODUCT ADVANTAGES

  • Superior sealing effect with the secondary lipLow axial housing heights
  • Secondary sealing lip provides extra protection against theingress of dirt particles
  • Easy assembly into closed grooves
  • Good sealing performance even at low pressures
  • Wide range of dimensions

APPLICATION

Construction machinery, fork-lift trucks, injection
mouldingmachines, Agricultural machinery, mobile
hydraulics, standardcylinders, loading platforms and
telescopic cylinders.

INSTALLATION

Easily assembled into closed grooves according to the minimum diameter values that are given in the below table. Open grooves or special assembly tools should be used for the values that are outside this table. Before installation the sealing element must be oiled with system oil.

NOTES

The permissible sealing gap values of K38 rod seal is given in the below table.
