546 (dynamic glide ring, single acting)
AF-546 has a rectangular glide ring section and is provided with a stepped sealing edge on the pressure side. On the opposite side, the profile travels under a flat wedge/angle. This special form of sealing profile helps to achieve a recovery effect. This means that the persistent oil film present on the cylinder wall during motion is conveyed back to the surge chamber. The addition of a chamfer on the O-ring contact surface reduces the strain on the O-ring.
Two-part composition, consisting of a dynamic glide ring and an O-ring.
Advantages:
- Very good static and dynamic sealing effect
- No stick-slip effect
- Excellent resistance to extrusion
- Same groove design as AF-541/547
- No stick-slip effect
- More stable and better performance then AF-541/547
Limitations on use
- Operation pressure: Up to 40MPa (400 bar)
- Velocity: Reciprocating up to 15 m/s
- Temperature: -40°C to 200°C
