(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
(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
