Applications, which hydraulic cylinder shaft reciprocates under high fluid pressure, represent the fluid power sector main group.

Applications, which cylinder shaft reciprocates under low fluid (air) pressure, represent the fluid power sector other main groups after hydraulics. These applications involve major parts such as pneumatic cylinders, valves and system components.

These are static seal applications, which are used no dynamic operation exists, like generally flange or connection points, metal joint surfaces or gear boxes, and oil filling gaps.

Rubber and rubber-metal parts in classical radial(rotary) shafts or linear shafts for hundreds of different special applications, from the brake calipers to refrigerator compressor, from pesticide pumps to axial fans.
