1. The automatic centering ability comes from the DF (45 - ° 45) ° combination of the arc groove. During installation, even if there is some deviation in the installation surface, it can be absorbed by the inside of the line rail slider by virtue of the elastic deformation of the steel ball and the transfer of the contact point, so as to produce the effect of automatic centering ability and obtain high-precision, stable and smooth movement.
2. Interchangeability Due to the strict control of the manufacturing accuracy, the size of the linear guide rail can be maintained within a certain level, and the slider has a retainer design to prevent the steel ball from falling off, so some series of precision are interchangeable. Customers can order the guide rail or slider as required, or separate the storage guide rail and slider to reduce the storage space.
3. Four row arc grooves are used in all directions with high rigidity, and the contact angle of four rows of steel balls is 45 degrees, so that the steel balls can reach the ideal two-point contact structure, and can withstand the load from up, down, left and right directions; When necessary, preloading can be applied to improve the rigidity.
