Pneumatic piston seal

Rotary seals are used in applications with oscillating or rotating movements in order to retain liquid lubricants and to prevent the penetration of dirt and water.

Profile P1 is particularly suitable for single-acting pistons in control cylinders, in servo controlled systems, machine tools and in construction machinery. Optimal sealing performance obtained if used in tandem with Guide Ring.Good back-transport of oil film due to special shape of sealing edge.

Piston Seal additive

The Synering® system is an advanced sealing concept designed to meet extreme demands regarding temperature, medium, etc. which cannot be covered by conventional sealing compounds.

Profile P3 is appropriate for dynamic applications as an alternative to an O-ring in situations where sealing performance and friction have to be optimised.Can be used in existing O-ring grooves.

Piston seal types

Profile P2 is suitable for double-acting pistons in control cylinders, servo-controlled systems, machine tools, quick acting and steering cylinders.Capable of sealing dynamic pressure from both sides (bidirectional) at high pressure.

Back-up rings are used for static and dynamic applications in connection with O-rings, to prevent extrusion of the O-ring into the diametrical clearance.

Profile P4 is suitable for double-acting pneumatic pistons, e.g. in control cylinders, servo assisted equipment, and in quick-acting cylinders.Can be used for pneumatic applications.
