QRH

(1) Super high load capacity in linear guideway, with the four rows of rollers 

arranged at a contact angle of 45-degrees, the QR series linear guideway has 

equal load ratings in the radial, reverse radial and lateral directions. The QR 

series has a higher load capacity in a smaller size than conventional, ball-type 

linear guideways.

(2) Low Noise Design With SynchMotionTM technology, rolling elements are interposed between the partitions of 

SynchMotionTM to provide improved circulation. Due to the elimination of contact between the rolling elements, 

collision noise and sound levels are drastically reduced.

(3) Smooth Movement In standard linear guideways, rolling elements on the load side of the guide block begin rolling 

and push their way through the raceway. When they contact other rolling elements they create counter-rotational 

friction. This results in a great variation of rolling resistance. The QR linear guideway, with SynchMotionTM

technology prevents this condition.

(4) The QR series is a type of linear guideway that uses rollers 

as the rolling elements. Elastic deformation of the linear 

contact surface, during load, is greatly reduced thereby 

offering greater rigidity and higher load capacities in all 4 

load directions.
