Publication number: 20090321216Abstract: A drift conveyor (1) has rollers (14) introduced into bearings (13) of a frame (12). An axle (143) of the roller (14) is received in a receptacle (1310) of the bearing (13), and a roller plate (15) presses the bearing (13) so that a first sealing region (1308) of the bearing (13) contacts a sealing region (152) of the roller plate (15). A rotary fastening region of the bearing (13) contacts a fastening region (153a) of the roller plate (15) and a second sealing region of the bearing (13) contacts the frame sealing region. One side of the bearing (13) has the receptacle (1310), the first sealing region (1308) and a rotary fastening region that prevents rotation of the bearing (13) with respect to the roller plate (15). An opposite side of the bearing (13) has a second region for sealing between the bearing (13) and the frame (12).Type: ApplicationFiled: August 7, 2007Publication date: December 31, 2009Inventor: Reinhold Weichbrodt
