PARKER Parker RS rotary sealing
1.RS rotary sealing presentation
High-strength thermoplastic slide ring and a rubber expansion ring RS rotary seal by a particular thermal stability of the composition.
Special geometry within a slip ring contact surface has alternating pitch (patent number: EP0643 243 B2) has a very beneficial effect on the lubrication of the seal. To reduce friction and wear plays an active role.
Expansion loop for the square cross-section, from the static sealing effect, compared with the O-ring in contact stress and deformation characteristics are good.
RS for sealed, we do not recommend for the outer seal both ends.
Slide ring material and geometry allows the maximum allowable pressure (and in case of pressure shocks) can use this structure, without the need for additional anti-extrusion rings. At the same time, it can also increase the radial clearance between the rotor and the stator without compromising any functionality.
R S can in principle be used as the outer seal both ends, however, can not be determined, we will recommend the use of C5 or C9 type of the company listed specifically.
2. Materials:
Standard slip ring material is a thermoplastic material (W5060) with a special thermal stability. Expansion loop Shore A70 standard (NBR) NBR rubber N3571.
If the expansion ring using a suitable synthetic rubber (HNBR, FPM), the same slip ring, temperature range up to 130 ° C.
If the special requirements (pressure, temperature, speed, etc.), please consult our service department in order to recommend the right materials and structures.
3. Application:
Working pressure: ≤500bar
Operating temperature: -35 to + 100 ° C
Surface speed: ≤0.5m / s
Recommended: p • V≤70 for L = 6.0 and 6.3
P • V≤40 for L = 4.1 and 4.2
Mainly used for rotation of the cam ring, the pivot drive, flexible tubing and other rotating wheel alternating sealing applications, but also for a hydraulic machine.
4. Installation:
This axial seals with particularly narrow for compliance with DIN ISO 7425 standard grooves. Favor rotational drive total installation length. By appropriate choice of materials, diameter 30mm above the rotor can be manually loaded; smaller than 30mm, we recommend axially open grooves.
