1. With self-adjustment ability - X-shaped (45ᵒ-45ᵒ) of curved groove on cross-section design makes it self-aligning. Even if small misalignment exists on the mounting surface, this design can help absorb it and maintain high precision, smooth and stable linear motion.
2. High rigidity, equal load on four-direction design - The 45-degree contact angle design of the four rows of steel balls and the raceway allows the steel balls to achieve the ideal two-point contact and can withstand the action and reaction force from the radial and lateral direction. Meanwhile, pre-load can be applied to increase extra rigidity if necessary. Reduce the combined height of the slide block and the slide rail, shorten the length of the slide block, to achieve miniaturization.
3. Interchangeable - Because of the strict control of the manufacturing process, the dimensional accuracy is stable and within the set tolerance. Besides the ball retainer design can prevent steel balls from falling out. Therefore when assembling, blocks are interchangeable within the same spec and still maintain consistency of pre-load and accuracy.
