C9R
The profile C9R is a further development of the profile C5R. Combined with the wear-resistant elastomer part, this profile was additionally provided with a back-ring. Thereby the pressure strength got increased and gap extrusion prevented, which with rotation, do to eccentricity often happens. This one sided agent seal, herefor is able to compensate higher pressure peaks.
ADVANTAGES ARE
- unempfindliche gegen Spaltextrusion
- easy to install
- also available in EPDM and FKM
APPLICATION RANGE | |
working pressure: | ≤ 4,0 MPa (40bar) |
operation temperature: | - 30 °C to + 100 °C (NBR) |
- 25 °C to + 200 °C (FKM) | |
sliding speed: | ≤ 0,2 m/s, recommendation: PxV ≤ 0,3 1) |
Often used with mobile- and machine tool-hydraulic, with low pressure swivel screw-fittings, as well as endseals, with rotary feed through, of construction equipment.
MATERIAL
Standard compound for the rubber sealing is a NBR-based elastomer (N3764), with a hardness of approx. 90 Shore A. The back-up ring is made of a polyacetal-based material (W5001).
MOUNTING INSTRUCTIONS
To ensure a perfect function, the groove width must be larger than the seal width (look at chart). The C9R is easy to install in closed grooves. While installing, first place the rubber part and later the back-ring. So the seal won´t be damaged, don´t pull it over sharp edges. Edges within the seal housing have to be provided with radii (look at mounting layout).
In certain cases (high temperature, speed, specific resistance to pressure a.s.o.) please contact with our application technology.
1) product from pressure (MPa) and sliding speed (m/s) should not exceed 0,3
