Robot Bearing as the spindle of the lathe adopts cross roller bearings, it reduces the time of the lathe's establishment, small ball Bearing for robotand the center of the spindle of the CNC vertical lathe has also been reduced, but its performance has been greatly improved. In addition, because the roller is arranged in cross and effective distance between rollers increase, improve the degree of rotation and stable performance, when the drive Roller Bearing roller rotation, just between the relative rolling and sliding phenomenon, so the CNC vertical spindle lathe consumption greatly reduced, reduces fuel consumption, relative for more environmental protection, reduce noise, Thin Section Ball Bearing,reduce the use of raw materials.
