The HIWIN-QH seriesThe partition is a grouping of hollow ring-like structures formed linear guideway with SynchMotionTM Technology possesses all the advantages of the HIWIN-HG series, and alsowith a through hole to facilitate circulation of the lubricant. offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the HIWIN- Because of the special lubrication path design, the lubricant ofLubricant QH linear guideway has broad industrial applicability. In the high-tech industry where high speed, low noise,the partition storage space can be refilled. refilland reduced dust generation is required, the HIWIN-QH series is interchangeable with the HIWIN-HG series. Therefore, the frequency of lubricant refilling can be decreased.The QH-series linear guideway is pre-lubricated.

When they contact other rolling elements they create counter-rotational friction. This results (1) Low Noise Design in a great variation of rolling resistance. The QH linear guideway, with SynchMotionTM technology prevents this condition. As the block starts to move, the rolling elements begin rolling consecutively and remain separated to With SynchMotionTM technology, rolling elements are interposed between the partitions of SynchMotionTM toprevent contact with one another thus keeping the element's kinetic energy extremely stable in order to effectively provide impoved circulation. Due to the elimination of contact between the rolling elements, collision noise andreduce fluctuations in rolling resistance. sound levels are drastically reduced.SynchMotion Type Conventional Type80 HG25 no grease50 HG25 no grease10QH25 no greaseQH25 no grease840 6705dB 30 4 dB(A)dB(A) Force(N)260 20 0-210 -450 -60 -8Time(0.05sec)40 -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 253391 T: 01827 288122F: 01827 253391E: email@example.com E: firstname.lastname@example.org 43"
