Solution for hydraulic challenges


Often, large hydraulic forces must be applied in linear movement, to lift, lower, move or just to keep loads. For this, the hydraulic cylinder is the crucial component of the machine and the cylinder design is an important link in the mechanical engineering field. Varying bulk productions and individual productions characterise the production processes and thus also the sourcing strategies of this industrial sector. The quality of the cylinder and the power transmission depends very much on the employed sealing and guide components, and the timely provision by a reliable partner like Seal Concept GmbH.

Many aspects should be taken into account to meet the needs of a dynamic, highly innovative industrial sector.
