The Hiwin QE series silent low assembly ball linear guide is based on a four column single arc tooth contact design, which reduces the combination height and shortens the slider length, making it very suitable for use in high-speed automation industry machinery and small equipment with space requirements. The QE series linear guide rail using SynchMotionTM technology is equipped with a patented synchronous coupling with oil storage function, which can effectively reduce noise during operation, improve smoothness, lifespan, and lubrication efficiency. It has a wider range of industrial applications and is more suitable for high-tech industries that require high speed, tranquility, and low dust emissions.
