The characteristics of VAV linear slider
Automatic centering ability
When DF from the circular arc grooves (45 ° 45 °) combination is installed by the transfer of the elastic deformation of steel ball and the contact point, even if the installation surface have some deviations, it can also be line rail slider internal absorption, producing automatic self-aligning ability to abtain high precision and stable smooth movement.
Due to strict control of manufacturing accuracy, the linear guide size can be maintained within a certain level, and the slider has the design of the retainer to prevent the steel ball from falling off. Therefore, part of the series precision is interchangeable. Customers can order the guide or slider as required, and can also store the guide and slider separately to reduce storage space.
All directions are highly rigid
The four-column arc groove is used to match the 45 degree contact Angle of the four steel balls, so that the steel ball reaches the ideal two-point contact structure, which can bear the load from up and down and left and right directions. When it is necessary, you can apply precompression to increase rigidity.
