PK 6N/6F
Piston seal PK 6N / PK 6F
is a double acting piston seal designed for pneumatic cylinders. It consists of a PTFE filled slip ring and an O-ring which activates it.Benefits
- Can operate at both very low and high pressure.- Convenient economical mounting reduces machining times.
- Suitable for high speeds.
- Due to low friction, no stick-slip effect even at very low speeds.
- High temperature cylinder sealing - with FPM O-ring.
In combination with various O-ring materials, this seal has a wide range of temperature and chemical resistance.
Recommended technical conditions
Pressure: < 16 barVelocity: < 4 m/s
Temperature: -30 to +80°C (standard materials)
Medium: lubricated and non-lubricated air
Material
Standard PTFE III / NBR 70 - PK 6N
On request PTFE III / FPM 75 - PK 6F (or other combinations)
Installation
The piston must be free of burrs and the cylinder tube must be tapered according to the mounting instructions in the catalogue introduction.
Fit the O-ring into the groove first (do not overtighten). Then, in one place, insert the PTFE compound ring into the groove and, using a circular motion, gradually stretch it around the entire circumference using a flat plastic band (details on request). For diameters up to 32 mm, we recommend an axially accessible stop space.
