The STAF MPHX09SN is a micro linear guideway belonging to the MPH series, crafted from high - quality materials with corrosion - resistance properties, ensuring its durability and reliability across various working conditions. In terms of physical dimensions, the assembly height (H) of the MPHX09SN is 10 mm, and the width (W) is 20 mm, presenting a compact structure. This compactness makes it well - suited for applications where space is limited, such as in precision instruments, small - scale automated machinery, or mini - electronic devices. The slide has a width (B) of 15 mm and a length (L) of 33.9 mm. These precise dimensions are engineered to enable smooth and accurate linear movement. For mounting, it is equipped with an M3 mounting thread (MQ), which simplifies the installation process and allows for a secure connection to other components within a mechanical system. The oil - hole diameter (Oil - H) is Ø1.3 mm, which plays a crucial role in providing proper lubrication to the moving parts of the guideway. Adequate lubrication reduces friction between the components, minimizing wear and tear and thus extending the service life of the guideway. In summary, the STAF MPHX09SN linear guideway is a reliable and space - efficient product, ideal for applications that require precise linear motion under light - to - medium - load conditions. The STAF Linear Guideway is high quality!
