Compact and high positioning: It is a compact design using nut and support bearing as an integral uint. 45-degree steel ball contact angle make a better axial load. Zero backlash and higher stiffness construction give a high positioning. Simple installation: It is installed simply by fixing the nut on the housing with bolts. Rapid feed: No inertial effect produced by the integral unit rotating and the shaft fixed. Can select smaller power to meet the rapid feed requirement. Stiffness: Have a higher trust and moment stiffness, because the integral unit have an angular contact construction. There is no backlash while rolling. Quietness: Special end cap design allows steel balls circulating inside the nut. Noise generated by high speed operation lower than ordinary ballscrew.
