ABSTRACT:
In a sealing arrangement for bores (2) in guide rails (1), particularly for linear assemblies, each bore (2) comprises a radially widened end portion (5) for receiving a screw head (4) of a fixing screw (3) and is adapted to be sealed in a plane parallel to an upper surface (10) of the guide rail (1) by a sealing plug (6) having a disc-shaped upper part (8) and a concentric shank (9), said sealing plug (6) extending in a sealing position in the end portion (5) of the bore (2), characterized in that an annular clamping washer (7) comprising a through-slit (11) in radial direction at one circumferential point is arranged in the end portion (5) between the upper part (8) of the sealing plug (6) and the screw head (4), and the shank (9) of the sealing plug (6) is pressed into a bore (12) of the clamping washer (7) whereby, with the help of the clamping washer (7), the sealing plug (6) is fixed in a simple manner in the end portion (5) of the bore (2) which is thus sealed.
