b'LinearMotionQ1 SeriesQuiet Linear Guideway with SynchMotion TechnologyLubricationThe development of HIWIN-QH linear guideway is based on a four-row circular-arc contact. The HIWIN-QH series linear guideway with SynchMotionTM Technology possesses all the advantages of the HIWIN-HG series, and also offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the HIWIN-QH linear guideway has broad industrial applicability. In the high-tech industry where high speed, low noise, and reduced dust generation is required, the HIWIN-QH series is interchangeable with the HIWIN-HG series.ConstructionRailBlockEnd capEnd sealBallThe SynchMotionBottom sealRetainerFeatures Bolt cap(1) Low Noise DesignWith SynchMotionTM technology, rolling elements are interposed between the partitions of SynchMotionTM to provide impoved circulation. Due to the elimination of contact between the rolling elements, collision noise and sound levels are drastically reduced.80 HG25 no grease50 HG25 no grease QH25 no greaseQH25 no grease 40705dB 30 dB(A) 60dB(A) 201050040 -100 200 400 600 800 1000 1200 1400 16001800 2000 0 2 4 6 8 10 12 14 16 18 20mm/s kHzT: 01827 288122F: 01827 253391E: email@example.com'
