Basic Dynamic Load Range: 13.88kN - 108.72 kN The development of QH linear guideway is based on a four-row circular-arc contact. The QH series linear guideway with SynchMotion™ Technology offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the QH linear guideway has broad industrial applicability in the high-tech industry where high speed, low noise, and reduced dust generation is required. The QH series is interchangeable with the HG series.
