DR 117

The DR 117 model is a single-acting low-friction seal with a flanged flange, which provides sealing on the inside in rotating or oscillating applications.
It consists of two elements: a PTFE collar (with loads) and a metallic spring that tensions the collar and maintains its circular geometry in all its perimeter, both inside and outside. The sealing lip has a protrusion on the inside that keeps the spring in place.
- U-shaped, V-shaped or helical springs.
- Part free of Stick-slip effect.
- Oscillatory motion.
The slip ring can be machined in various PTFE formulations and also in polyurethane.
