Check the listing for details. NEWPORT 460A SERIES XY MICROMETER STAGE D200. Condition: Used. Listed at 451.23 USD. The 460A-XY 0.5 inch (12.7mm) Travel Two-Axis Quick-Mount Linear Stages has an integrated, yet modular, design allowing for increased versatility. The 460A-XY is integrated not only for precise, orthogonal motion but also for exceptionally low profile and features all aluminum construction with hardened ball bearings running along opposing pairs of polished and hardened stainless steel rods. This offers exceptional straightness of travel, but a lower load capacity than our crossed-roller bearing stages. The stages are spring loaded against the drive actuator for backlash free motion. Vertical-drive assemblies carry the load through the actuator spindle rather than the springs for positive load support. Two actuators are required and are ordered separately.
