With over 50 years of experience, RSD cross-roller guides are the worldwide standard in high-tech applications for short to medium travel. They are used for precise linear motion providing zero play, high accuracy, almost zero friction, and outstanding reliability. Depending on the requirements the anti-friction guides can be fitted with either ball cages (ball guides) or crossed roller cages (cross-roller guides). Ball guides are used in light load applications, providing smooth running and low rolling friction. Cross-roller guides are used for applications requiring medium-high loads, high stiffness, and precision.
