Publication number: 20080187262Abstract: The invention relates to a sealed radial rolling bearing, in particular a wheel bearing for a motor vehicle, which substantially comprises an outer bearing ring and an inner bearing ring and a plurality of rolling bodies which roll between the bearing rings and are held with uniform spacing relative to one another by means of a bearing cage. Here, in each case one radially arranged sealing element extends between the bearing rings at each side at a distance axially from the rolling bodies, said sealing element having one or more sealing lips which are connected to the outer bearing ring and some into contact with a centrifugal ring which is connected by means of a press fit to the inner bearing ring.Type: ApplicationFiled: April 28, 2006Publication date: August 7, 2008Applicant: SCHAEFFLER KGInventors: Peter Niebling, Ernst Masur, Hartwig Waldert, Georg Schoener
