The NB SLIDE WAY is a non-recirculating, Crossed Roller linear motion bearing utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required. The NB SLIDE WAY NV type comprises precisely ground rails and R-retainers with built-in STUDROLLERs and precision rollers. The rails have been optimally designed so that the STUDROLLERs move smoothly, and the STUDROLLERs and precision rollers incorporated in the R-retainers enable slip-free operation between the raceway surface and the rollers resulting in motion with minimal frictional resistance. SV and SVW types consist of precision ground rails and precision caged-rollers. Since caged-rollers do not recirculate, there is only a minimum frictional resistance fluctuation. Also, there is a minimum difference between the static and dynamic frictional resistances. Suitable for Minute Motion Because the frictional resistance is extremely small and here is only little difference between the static and dynamic frictional resistances, the NB SLIDE WAY is well suited for minute motion, resulting in highly accurate linear movement. Low-Speed Stability Since the frictional resistance fluctuation is small even under low-load conditions, stable motion is obtained at from low to high speeds.
