The RB series of ultra-low profile roller guides from NSK Precision America are designed to meet the rigorous demands of the machine tool industry. Compared with NSK’s conventional RA series roller guides, the series offers a 26% reduction in overall height, which helps downscale equipment and lower the center of gravity of precision/positioning tables.
Optimizing the rolling contact conditions yields high capacity and rigidity, which is a result of configuring the internal dimensions so as to accommodate slider deformation (patent pending). As a result, equipment can be downscaled without sacrificing load capacity or high rigidity. Additionally, NSK’s K1™ Lubrication Units are available to ensure long-term, maintenance-free operation.
The RB series is available in five preloaded sizes ranging from RB30 to RB65 with 23 slide model types available.
