Four row circular arc structure, high rigidity, long service lifeFour row circular arc guideway structure, while four rows of steel balls bear the load, the circular arc groove eliminates the differential friction of the two row Goethe structure, even if the preloading is increased, it can still maintain a high smoothness and a small number of friction, which can greatly improve the rigidity and prolong the life of the guideway.
