R Series-High Rigidity Roller Type Linear Guideways

- High Rigidity Roller Type Linear Guideways -


R Series

RW-CC/RW-HC

Applicable industries of R series:
CNC machining centers,Heavy duty cutting machine,CNC grinding machine

(1) Optimal design
FEM analysis was performed to determine the optimal structure of the block and the rail. The unique design of the circulation path allows the R series linear guideway to offer smoother linear motion.
(2)Super high rigidity
The R series is a type of linear guideway that uses rollers as the rolling elements. Rollers have a greater contact area than balls so that the roller guideway features higher load capacity and greater rigidity. The figure shows the rigidity of a roller and a ball with equal volume.
(3)Super high load capacity
With the four rows of rollers arranged at a contact angle of 45-degrees, the R series linear guideway has equal load ratings in the radial, reverse radial and lateral directions. The R series has a higher load capacity in a smaller size than conventional, ball-type linear guideways.
(4)Operating life increased
Compare with the ball element, the contact pressure of rolling element is distributed on the line region. Therefore, stress concentration was reduced significantly and the R series offers longer running life. The nominal life of R series can be calculated by using Eq.

 Note: 1. 1kgf = 9.81N

 

 

           2. The theoretical dynamic rated load is C100R,if necessary C50R conversion formula is as follwos : C50R = 1.23 x C100R
