Pre-Selection Hydraulics – Piston Seals

Temperature figures refer to mineral oils. Due to the large choice of media with different and varying additives, which is not always easily comprehensible, the above operating limits are only recommended values. We recommend testing resistance in the specific case.

Individual instances of the operating limits stated may be exceeded taking into account the related operating conditions.With a long duty cycle, stop-start operation or other difficult operating conditions it is recommended that these values are notsimultaneously exploited to the full.
