description
rod seal S09-SD consisting of profile ring and O-ring as a preload component
application
category of profile
machined or molded/standard/trade product.
double acting
the RS 09-FI seal is designed for use as a piston seal.
area of application: hydraulics advantages
rod seal for lower pressure range with properties of :
- low friction
- low housing height
operating parameters & material
| material | temperature°C | max-surface speed | max-pressure | |
| sealing element | energizer | |||
| PTFE +40%bronze | NBR 70 SH-A | -30 °C … +100 | 2 m/s | 160 bar (16 MPa) |
the stated operation conditions represent general indications. it is recommended not to use all maximum values simultaneously. surface speed limits apply only to the presence of adequate lubrication film.
1 pressure ratings are dependent on the size of the extrusion gap.

gap dimension
the decisive factor for the function of the seal is the largest gap dimension occurring during operation on the non-pressurised side of the seal.
we recommend a metal guide H8/f7.
fitting & installation
careful fitting is a prerequisite for the correct function of the seal.
seal & housing recommendations
please note that we are able to produce those profiles to your specific need or any non standard housing. for detail measurements, please see JET SEAL PARS catalog…
