Linear stage E-NFZ240-Z series

verticallinear motor-drivenfor heavy loads

● Design Features ● Designed for high-performance scanning and inspection ● Active air preload on all air-bearing surfaces ● Linear encoder feedback provides sub-nanometer resolution ● High stiffness for heavy loads and excellent geometrical performance ● with travels from 50 and 100 mm ● Integral counterbalance Air-Bearing Design for High Dynamic Performance The E-LMT145-Z incorporates an air-on-air preload on both the vertical and horizontal surfaces. The opposing thin-film pressure maintains the bearing nominal gap tolerance. This design, in addition to the large air-bearing surface that distributes the load over a large surface area, results in a stage with outstanding stiffness that is ideal for heavy or offset loading. proprietary manufacturing techniques result in a stage with unsurpassed geometric characteristics, which maximize performance by yielding superior pitch, roll, yaw, straightness and flatness specifications. The driving force behind this stage is Precision-stage series brushless linear servomotor. The utilizes an ironless forcer, which means there is zero cogging and no attractive forces, resulting in unsurpassed smoothness of motion. Our totally noncontact air bearing, noncontact linear motor drive and noncontact feedback device ensure years of maintenance-free operation at the high performance levels expected of equipment. Because there is no mechanical contact between moving elements, the E-LMT145-Z experiences no wear or reduction in performance over time. Service life is virtually unlimited and because there is no lubrication – only clean, dry gas – air bearings are ideal for cleanroom and medical applications.
