Dynamic Slide Ring (Single Acting)

Single acting piston seals of the AF-441 series are preferentially used in hydraulic cylinders with unilateral pressure application. Various material combinations ensure high functional reliability
and long life over the entire range of pressures and velocities with minimal friction, and with various temperatures and media.

Two part composition, consisting of a dynamic seal ring and an O-ring

Advantages:

• Outstanding shear characteristics
• No stick-slip effect
• Good dynamic and static sealing
• Great abrasion resistance, and a long service life
• Designed for assembly on either a single acting piston, or in combination with other seals

Limitations:

• Operation pressure: Up to 35MPa (350 bar)
• Velocity: Reciprocating up to 15 m/s
• Temperature: -40°C to 200°C
