SPGW Hydraulic Cylinder Piston Rings Excavator Coffee PTFE Spgw Piston Seal

SPGW heary duty piston seals are designed for double acting hydraulic cylinders used in heary duty
applications. They consist of PTFE ring,2 POM support ring and NBR pressure ring. Some advantages are its
simple design, high linear velocity values, non-bonding property on the surface in long static cases, low
friction, wider permissible gaps and long life sevice.Therefore, SPGW is very suitable for heary duty
applications.
