What are the advantages of cross roller guides? 

1. Low mechanical energy consumption and high precision, fast speed and large carrying capacity

2, rolling friction is small, stability is good;

3, the contact area is large, the amount of elastic deformation is small

4, effective movement body, easy to achieve high rigidity, high load movement;

5. Flexible structure design, convenient installation and use, and long service life;
