The development of LM-TECH SH linear guideway is based on a four-row circular-arc contact. The SH series linear guideway with SynchMotionTM Technology offers smooth movement, superior lubrication, quieter operation and longer running life. Therefore the SH linear guideway has broad industrial applicability. In the hightech industry where high speed, low noise, and reduced dust generation is required, the SH series is interchangeable with the LM-TECH HT series.
