5 kinds of precision available for your choice: general level, advanced, precision grade, ultra-precision stage, the top. Heavy duty type MSA and MSB series of low linear slide assembly with four 45 ¡ã arc-contact and contact angle of the ball out in the design, provision of radial, radial and transverse direction against the direction of the same four rated load capacity, regardless of X , Y, Z axis such as the various installation methods can be used, and can maintain a low friction conditions imposed under the uniform preload, increased rigidity of the four directions by the force, particularly suitable for high precision and high load of Exercise . Design patent of lubricating oil, grease can be uniform loop cycles, no Zhuru each installation are available on a variety of the best lubricating effect, and improve the overall smoothness and service life of walking, to achieve high precision and high reliability and smooth and stable demand for linear motion. ABBA linear guide size:6*9.5*8.5.
