Abstract
A sealing sleeve seals off a shaft rotating in a rotary joint coupling having a joint outer part and a coupling end facing toward the sealing sleeve. The sealing sleeve includes a first end and a second end. The second end has a larger diameter than the first end and is connected seal tight with the joint outer part and the first end is connected seal tight with the shaft. A first section of the sealing sleeve extends from a lip seal and is in contact engagement with the shaft. The first section has an inner periphery and a plurality of inner grooves distributed over the inner periphery. A second section extends from the first section at the coupling end. The second section has an inner periphery and sawtooth-shaped rib-like projections aligned toward the shaft and the rib-like projections have tips in contact engagement with the shaft.
