boom concept. These ‘circular
       welding columns’ weld the internal
       and external joints of the long steel
       hoops that form the cones of wind
       turbine towers. In terms of capacity,
       the machines can accommodate
       cones measuring up to 7m in length
       and 5m in diameter.
         To help expedite its welding
       process, Talleres Ganomagoga
       required a way of moving a machine
       along the length of a tower as it
       grew in size during manufacture. By
       collaborating with the expert team
       of engineers at NSK, this vision
       soon became reality.
         Today, the company joins the
       cones together by manoeuvring a
       circular welding column along a specially devised   special welding machines in line with production
       system of linear sliders and rails from NSK’s precise   demands. NSK’s RA series leverages the company’s
       and reliable RA series. The combination of NSK   combined expertise in roller bearing and linear
       super high-load linear sliders and NSK rails (in   guide technologies. The optimum size of the rolling
       lengths of 9.225m and 7.8m) helps Talleres   element, along with the special shape of the roller
       Ganomagoga achieve precise movement of its   slides and rails, ensures super high load capacity
                                                and equally impressive rigidity.
                                                   Long life and smooth operation are
                                                mandatory requirements in the application at
                                                Talleres Ganomagoga, which seeks zero
                                                defects during its welding processes. Here,
                                                the use of NSK K1 lubrication units mean
                                                long-term maintenance-free operations, while
                                                high-performance  seals  (supplied  as
                                                standard) block the entry of foreign matter –
                                                a highly important factor in operations such
                                                as welding where the potential contamination
                                                risks are high.
                                                   RA series roller guides also provide super-
                                                high accuracy and smooth motion, factors
                                                that deliver repeatable and stable positioning
                                                time after time.
