Caged ball LM radial type guide where balls roll in four rows of raceways precision-ground on an LM rail and an LM block. The ball cage eliminates friction between balls and increases grease retention, thus achieving low noise, high speed, and long-term maintenance-free operation. Lastly, using a ball contact structure highly resistant to loads in the radial direction minimizes radial displacement under radial loads and provides stable, highly accurate motion.
