DescriptionSpecifications Models Literature
460A-XYZ and 460A-XYOrder actuators separately.

The 460A Series Low-Profile Integrated Ball Bearing Linear Stages have an integrated, yet modular, design allowing for increased versatility. The XY Model is integrated not only for precise, orthogonal motion but also for exceptionally low profile. The Z Axis Stage/Bracket is user removable allowing conversion of an XYZ Model to an XY Model or conversion of an XZ Model to an X Model. The 460A 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.


Preloaded precision ball bearing movements provide reduced friction and capability to make small controlled movements. Bearings are captured in hardened steel rod guides.
