Description Corrosion-resistant coating Resist CR, matte silver hard chrome plated High torque capacity Top rigidity in all load directions Top rigidity in all load directions High torque capacity For mounting from above with plastic mounting hole plugs Corrosion-resistant coating Resist CR, matte silver hard chrome plated 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. Corrosion-resistant Resist CR coating Steel ball guide rail with corrosion-resistant coating, mat silver finish, hard chrome-plated. Ball guide rails with coated end faces ▶ Coated end faces, chamfers and end-face thread, material numbers: – R16.. ... 41 or R16.. ... 71 ▶ Multi-part ball guide rails are chamfered on two sides at the joints.
