The RS rotary sealing set consists of a high-strength thermoplastic slide ring with particularly stable thermal properties and an elastomer preloading element. The special contact surface geometry at the inner diameter of the slide ring with the patented (EP 0 643 243 B2) alternating pitch has a major benefical effect on the lubrication of the seal. This has a positive impact on both friction and wear. The preloading element responsible for the static sealing function has a rectangular cross section. Compared to O-rings, this has advantages with regard to contact load (sealing) and deformation behavior (pumping inside the groove). The dynamic interior sealing method is preferable. We do not recommend a dynamic exterior sealing arrangement. The slide ring compound used and its geometry allow use of the seal even under maximum permissible pressure (and in case of pressure peaks) without requiring additional anti-extrusion rings. At the same time, it is possible to take maximum advantage of the diameter play between rotor and stator without any functional impairment. In principle, the seal can also be used as an exterior end seal. In case of doubt, however, we recommend our C5 or C9 product series.

• Enhanced sealing performance in non-pressurized conditions.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Long service life thanks to application-optimized compounds.
• Insensitive to pressure peaks.
• Improved lubrication due to pressure medium deposit in the dynamic contact area.
• Extremely high extrusion resistance.
• Installation in closed and undercut housings.

Range of application:
Primarily for alternating sealing of rotary applications in rotating tracks, pivot drives, hose reels, and in machine tool hydraulics.
