Hr-separated guide rail (a total of 13 products)
THK linear guide can separate type (4 direction equal load) -HR type
The steel ball is rolled along two rolling surfaces which have been precisely ground on LM track and LM slide. By assembling the end cover plate on the LM slider, the steel ball column moves in a circular manner. The LM slider USES a holding plate to hold the ball in place, so the ball doesn't fall off
Structure of angular contact, LM orbit 2 column steel ball rolling and rolling are angled 45 angular contact respectively. Thus, after assembling a set of two LM tracks and LM sliders that will be used in the same plane, the same load can be carried in four directions (radial, inverse radial and lateral). Moreover, due to the low profile height, a small and stable linear guide mechanism can be obtained. In addition, the clearance adjustment is relatively easy, and the error absorption capacity of installation is also excellent.
Installation is simple
Compared with the cross roller guide, the HR type is easier to adjust the clearance and higher accuracy.
Automatic centering ability
Even in the case of poor parallelism and levelness of the two shafts, the automatic centering ability effect of the front combination (DF combination) of the arc groove can absorb the installation error and achieve smooth movement under the application of preloading
4 direction equal load
2 axis parallel to the install and use, to make the LM slider on the four direction (radial, the radial and lateral) have the same rated load, the steel column is designed according to the contact Angle of 45 configuration, so whatever the installation position can be used.
Cross - section dimension similar to cross - roller guide
The HR type is the infinite movement type that the retainer does not move, so there is no deviation of the retainer like cross roller guide. In addition, the section size of the HR type is similar to the cross roller guide, so it can be interchanged with the cross roller guide.
Also available in stainless steel
LM sliders, LM rails, steel balls can also be made of stainless steel
Note)The symbol M represents the stainless steel used in the LM module, LM track and balls. As a result, models marked with such symbols are highly resistant to corrosion and environmental damage.
