A NEW Roller Guide
for the NEW Generation





A new, innovative, roller guide.
An integration of ultra-high rigidity, ultra-high motion accuracy,
and ultra-high damping capability.



Deformation decreased by reducing the load,
and the EXRAIL was able to achieve 1.5 times higher rigidity
than conventional roller guides.

● Incorporation of multiple needle rollers, which are longer and smaller in
diameter
than conventional rollers, reduces the amount of load per roller.

● Reduced load means less deformation, and the EXRAIL was able to achieve 1.5
times higher rigidity.



Reduced rolling element passage vibration＊ to less than half
by dispersing load on to multiple miniature rollers.

● By dispersing the load on to multiple miniature rollers,
the rolling element passage vibration＊ is reduced to less than half.
＊The periodic postural change due to the amount and position of the rolling
elements supporting the load.



Frictional resistance generated
by multiple rollers improves vibration damping capability
to more than 1.5 times than that of conventional types.

● Dynamic friction becomes relatively larger since the number of rollers is
increased,
and time for convergence of oscillation is shortened.
This allows vibration damping to be more than 1.5 times higher
than that of conventional types in the market.



Needle rollers and the latest innovative technology are incorporated
to meet expectations for a roller guide of the new generation.


INCORPORATION OF NEEDLE ROLLERS

Multiple rollers allow the load to be dispersed.
In addition, longer roller length increases the contact
surface between the roller and the block/rail,
and reduces contact pressure.




LONG-TERM MAINTENANCE FREE

Contact of lubricated resin material and rollers contribute to extended
re-lubrication intervals.
