摘要:
A radial-shaft sealing assembly includes a sealing lip disposed on a support ring. A cylindrical portion of the sealing lip that abuts on a rotatable shaft contains an elastomeric material and has a profiling for pumping oil or lubricant back to an oil side of the sealing assembly. The profiling includes first and second annular ridges disposed in parallel, and first and second groups of radially-projecting pumping elements disposed therebetween and distributed around the circumference of the cylindrical portion. Each pumping element extending at an angle (α) to the circumferential direction (U) of the cylindrical portion, but the first group of pumping elements has an opposite orientation to the second group of pumping elements.
