The profile KA rotary sealing set consists of a fabric-reinforced rubber sealing part and two back-up rings to increase the stability and to prevent extrusion into the gap, especially for applications where eccentricity occurs. Due to the special design of the dynamic surface a “grease depot” will be built up retaining the lubrication film and avoiding dry operation.

• Enhanced sealing performance in non-pressurized conditions.
• Robust seal profile for harshest operating conditions.
• Extreme wear resistance.
• Insensitive to pressure peaks.
• High temperature resistance in case of suitable compound selection.
• Extremely high extrusion resistance.
• Installation in closed and undercut housings.

Range of application
Mainly for applications where the pressure alternates from one side of the seal to the other, such as pivots for rotating track rings, swivel joints, hose reels, and in machine tool hydraulics.

Rotary sealing set Praedifa series KA is available in the following compound:
