The 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.
High Rigidity and High Load Capacity :
Compared to the ball elements, the rollers provide a larger contact area and less elastic deformation, thus the NV type 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
The slide way NV, SV, SVW and slide table SVT
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.
In the SVT type slide table, the SV type slide way issandwiched between an accurately machined steel table and bed. In the SVTS type, the anti-corrosion SVS type slide way is sandwiched between an accurately machined aluminum table and bed.
Multiple benefits :
