The NB SLIDE WAY is a non-recirculating crossed roller slide way utilizing precision rollers. It is used primarily in optical and measurement equipment where high precision movement is required. Precision rollers are used as rotating elements. Since they do not recirculate, there is less frictional resistance fluctuation. Additionally, there is little or no difference between the static and dynamic frictional resistances.
The NB GONIO WAY is a curved crossed roller slide way utilizing low friction, non-recirculating, precision crossed rollers. It is used when there is a need to change the gradient or obtain an accurate gradient angle without changing the center of rotation in high-precision optical and measurement equipment.
