The 460A-XYZ 0.5 inch (12.7mm) Travel 3 Axis Quick-Mount Linear Stages has an integrated, yet modular, design allowing for increased versatility. The Z Axis Stage/Bracket is user removable allowing conversion of an XYZ Model to an XY Model. The 460A-XYZ 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. Three actuators are required and are ordered separately.
