The GER S.E. profile belongs to the family of piston seals, fitted on the piston to separate the two chambers of the hydraulic cylinder.

Materials and operating conditions

  • Materials: PTFE + bronze + NBR, PTFE + glass fibre + NBR and polyurethane (PU)
  • Temperature: -30 °C to +130 °C
  • Maximum pressure: 600 bar
  • Maximum speed: 15 m/s
  • Catalogue sizes: 77 (inner diameter from 5.1 to 682.7 mm)

Indicative values: actual limits depend on the fluid, surface finish and fitting tolerances.

Where it is used

They are essential when overhauling cylinders on excavators, loaders, tractors and presses: a worn piston seal causes internal bypass and loss of force.

How to choose GER S.E.

  • Choose single- or double-acting according to how the cylinder works.
  • Check the bore, groove bottom diameter and groove width on the piston.
  • Filled PTFE (bronze, glass or carbon): minimal friction and no stick-slip, suitable for high speeds.
  • NBR: the standard compound for mineral oils and greases, suitable for most hydraulic cylinders.

Measure the cylinder bore (D), the groove bottom diameter on the piston (d) and the groove width (H), then enter the values in the table filters.

Frequently asked questions

Which materials is GER S.E. available in?

GER S.E. is available in PTFE + bronze + NBR, PTFE + glass fibre + NBR and polyurethane (PU). The stated working temperature ranges from -30 °C to +130 °C.

What is the maximum pressure for GER S.E.?

According to the technical data, GER S.E. works up to 600 bar at speeds up to 15 m/s. The real limit depends on fluid, temperature and extrusion gap.

How do I find the right GER S.E. size?

Measure the cylinder bore (D), the groove bottom diameter on the piston (d) and the groove width (H), then enter the values in the table filters.
