AF-446

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
