MSC stainless steel series linear guide rail adopts 2 columns of Goethe arc contact type and 45° contact Angle steel ball design, providing radial, radial and transverse four directions of the same load rating capacity, no matter X, Y, Z axis installation can be used. The design of miniaturization and low friction resistance is suitable for miniaturization equipment. With the design of lubricating oil road, it can evenly inject lubricating oil into each circulation circuit. No matter various installation methods, it can obtain the best lubrication effect, and improve the overall smoothness and service life, to achieve high precision, high reliability and smooth and stable linear motion requirements.
