Composites seals

Composite seals are particularly well suited for sealing pistons and rods in hydraulic and pneumatic working cylinders.

Types
Composite seals MRA/MRR Type MRA and MRI are double-acting composite seals. They are primarily used with alternating directions of pressure (e.g. piston seals).

Composite seals SRI/SRA Type SRI and SRA are single-acting composite seals. They have proven to be particular effective for sealing piston rods. The sealing effect is produced by the inherent preload of the PTFE profile ring vis-à-vis the rod and the preload of the rubber-elastic O-ring in the groove area. With rising system pressure the radial contact pressures increase as well. Bauart SRI	SRI/SRA Type SRI and SRA are single-acting composite seals.

Rotary composite seals MRR Rotary composite seals are particularly well suited for sealing rotating shafts, such as in rotary transmissions, rotary distributors, rotary joints and swiveling motors in mobile hydraulics and machine tools. A specially designed slide ring based on PTFE or PE is pressed against the surface by an elastomer O-ring and additionally activated by the system pressure.
