HIWIN QR Series - Quiet Roller Type Linear Guideway

上銀科技 HIWIN QR Series - Quiet  Roller Type Linear Guideway

(1) 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. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to prevent contact with one another thus keeping the element's kinetic energy extremely stable in order to effectively reduce fluctuations in rolling resistance.

(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) 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.

(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.


Especially for the industries in which high speed, low noise, and high rigidity environment are required
