AF-546

Dynamic Slide Ring:

Slide ring section is rectangular 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 persistant oil film present on the cylinder wall during motion is conveyed back to the surge chamber.

Advantages:
  • Very good static and dynamic sealing effect
  • Stick-slip free as all other PTFE parts
  • Very good resistance to extrusion
  • Same groove design as AF-541
  • Can be made for all diameters up to 1.200 mm
  • Low friction in start operation
  • Stick-slip free operation for precise control
  • More stable and better performance then AF 541

Limitations on Use  
Operating pressure Up to 40 MPa (400 bar)
Velocity reciprocating to 15 m/s
Temperature -40 to +200 °C (depending on O-ring material)
