An innovative parabolic profiled rolling grooves for linear guide way is disclosed. Cross sectional profile of at least one of the ray-way and the slider grooves is configurated into a parabolic curve so as to avoid the balls to comprehensively contact the grooves and seriously increase the frictional loss. With the rolling grooves constructed as such, the mechanical durability and the loading ability can be definitely improved. |
