QR series - Roller Type Linear Guideway,
with SynchMotionㆍ Technology

QR series offers super high rigidity and very high load capacities. The QR series with SynchMotion* Technology offers
low friction, smooth movement, quieter operation and longer running life. In the industry where high accuracy, low noise and high rigidity is required, the QR series is interchangeable with the RG series.

Advantages and features

Model Number 

QR series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these twotypes 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.
