1) Auto-alignment ability
The DF (45-degree 45) combination from the arc groove can be absorbed by the slider of the track by the elastic deformation of the steel ball and the transfer of the contact point, even if the installation surface is somewhat deviated, so as to produce the effect of self-aligning ability and obtain high precision and stable smooth motion.
Due to strict control of manufacturing accuracy, the dimension of linear guideway can be maintained at a certain level, and the slider has retainer design to prevent steel beads from falling off. Therefore, some series of accuracy can be interchangeable. Customers can order guideways or sliders as needed, and can store guideways and sliders separately to reduce storage space.
(3) High rigidity in all directions
Using quadrilateral arc groove and 45 degree contact angle of four rows of steel beads, the steel beads can reach the ideal two-point contact structure, which can withstand loads from the upper and lower directions and from the left and right directions. When necessary, preloading can be applied to improve rigidity.
