Abstract
A seal arrangement with a centrifugal ring for a sealing between a rotatable bearing part and a static bearing part. The centrifugal ring has a first end piece, which forms both an outer circumference of the centrifugal ring and a cutoff edge located on a disk-shaped outer face. The seal arrangement reduces the coefficient of friction without having to accept any loss of sealing effect, but in which the seal arrangement nevertheless remains cost-effective to manufacture. For this purpose, the centrifugal ring has a second end piece. The end pieces together form a first collecting channel in the vicinity of the cutoff edge and the end pieces each form an annular seal gap with a static bearing part.
