PTFE Rotary Seal Set-type TR
PTFE rotary Glide Seal sets are mainly used to seal rotating transmission leadthroughs or pivot drives and are characterized by their special low stick-slip tendency. To guarantee operation even under difficult conditions, the gliding surface has circumferential lubrication grooves.
We offer type RS as standard profile for rotary glide sealing application. Other profiles can also be provided upon request.
If the rotary seal set is used as end seal, a protective wiper should be fitted. The standard material combination is carbon filled PTFE and NBR (O-ring).
TR rotary seal is designed for inside sealing in bi-directional pressurization applications such as rotating track bushings, swivel joints, hose reels, and in machine tool hydraulics. A wiper ring near opening is recommended if TR seal is used as an end seal.
