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.

High Rigidity and High Load Capacity

Compared to the ball elements, the rollers provide a larger contact area and less elastic deformation, thus the NB SLIDE WAY has high rigidity and high load capacity. With new NV rail design, the roller contact area is increased by 30 to 58%. The number of effective rollers is increased by narrowing the roller pitch. Thus, the NV type has the load rating that is 1.3 to 2.5 times that of the SV type.

Low Noise

The SLIDE WAY never produces recirculation noise nor rollercontact noise due to a use of roller cage, resulting in quiet motion.

All Stainless Steel Type Available

The anti-corrosion SVS/SVWS SLIDE WAYs have all stainless steel components, making them ideal for use in clean room applications.

※To the NV type, fastening plates are attached for the purpose of maintaining the center position of the R-retainer before assembly.


STUDROLLER System (Rivet Roller Structure)

The STUDROLLER system is based on a new concept to provide complete prevention of roller cage slippage during operation. This system permits usage in all orientations and positions.



NV形The NV SLIDE WAY consists of a set of four rails, two R-retainers, and eight end pieces. It permits flexible design of the table which will best suit your application.

SV形The SV SLIDE WAY consists of a set of four rails, two R type roller cages, which have precision rollers in a cross arrangement, and eight end pieces. The all stainless steel option makes it suitable for use in corrosive environments.

SVW形The SVW SLIDE WAY consists of two SV-type rails, one W type rail, two R type roller cages, and eight end pieces. The use of a W-type rail serves for a compact design. The SVWS type is also available with all stainless steel components.
