The plastic cable and hose carrier TUBE TKA55 is leak tight and thus suitable for applications in dirty environments, where chips and dust are created. It has minimum gap widths and a smooth side belt contour. The uniform, extremely tight construction most effectively prevents the entering of dirt and dry as well as wet chips, a factor that normally fosters chain wear and also impairs the service life of cables and hoses. The very narrow gap width was achieved by a form-closed redesign of the covers. In addition they protrude over the side belts and enclose these most accurately. The smooth and dirt repellent side belt contour with encapsulated stroke system also prevents the entry of foreign matter and protects the function reliably. With an integrated sound-proofing the chain is quiet and, due to the polygonal behaviour in the bend radius (BR), the chain runs very smoothly. The covers can be loosened either inside or outside and thus enable quick installation of cables and hoses and inspection work.
