Development of eight-grooved linear motion ball guide with dimensions conforming to the ISO standard

Abstract

In the fundamental performance of linear motion ball guides, high accuracy, high stiffness, and long life are required. The eight-grooved linear motion ball guide (8-grooved LMBG) with maximized these performances has already been developed and launched. Although the 8-grooved LMBG has almost satisfied customers regarding these performances, it is not compatible with ordinary LMBGs because it does not conform to the dimensions of LMGB in the ISO standard. Therefore, a newly 8-grooved LMBG based on the ISO standard has been developed.
