Description Very high torque load capacity Top rigidity in all load directions Top rigidity in all load directions Very high torque load capacity Double-rowed for mounting from above Plastic mounting hole plugs No extra space needed at rail ends Features Observe the notes for mounting! Please request the "Mounting Instructions for Ball Rail Systems". Product description Ball rails can be cut to the length required by the customer. The maximum lengths for one-piece guide rails can be found in the "Technical data" chapter. If longer rails are required, Bosch Rexroth supplies them as composite ball guide rails. Attention! Size 20/40: New Ball Rail Systems with different ball diameters. Not interchangeable with the old 20/40 size!
