ABSTRACT:
The invention relates to a device (1) for sealing the ball side of a bearing of a roller journal (2), comprising a journal bushing (3) which is drawn to the roller journal (2), said journal bushing being associated with a bearing ring (5), a bearing bushing (7) which is mounted in an insertion piece (6), also comprising radial shaft seals which are associated with the insertion piece via a holder (11) and which are provided with radial lips (13, 13) which co-operate with the bearing ring (5) and a sealing arrangement (16) which is arranged upstream from the radial shaft seals so that the roller (4) can roll. The aim of the invention is to improve said device in such a way that it can be produced and operated economically such that it consists of only a small number of parts and has an improved sealing effect. According to the invention, the holder (11), the radial lips (13, 13), and a sealing lip (15, 15′) of the sealing arrangement (16) form one unit which is sealingly connected in a detachable manner to the insertion piece (6).
