Small friction, no sticking phenomenon, smooth start, no crawling even at low speed.

The groove is simple and the cross-sectional size is small

Good wear resistance, dimensionally stable

Very good compatibility with hydraulic media

High temperature resistance, good extrusion resistance

While rotating, it can withstand certain reciprocating motion.


2. Materials

Sealing slip ring: filled with polytetrafluoroethylene (PTFE). According to different working conditions and sealing requirements, different filling materials and filling processes can be selected, please contact us for details.
