HIWIN QR Series Quiet Roller Type Linear Guideway

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.

FEATURE

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.

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.

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.

APPLICATIONS

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

Model Number of QR Series

QR series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these two types are the same as one another. The main difference is that the interchangeable type of blocks and rails can be freely exchanged and they can maintain p-class accuracy. Because of strict dimensional control, the interchangeable type linear guideways are a wise choice for customers when rails do not need to be matched for an axis. The model number of the QR series identifies the size, type, accuracy class, preload class, etc.

(1) Non-interchangeable type
(2) Interchangeable type
Model Number of RG Block
Model Number of QR Rail (QR and RG share the identical rails)
