XY Linear Positioning Stage – XYR™
The XYR™ linear positioning stage is a low-profile XY platform designed for precision positioning and is one of Dover Motion’s most versatile and popular offerings. It is designed using stiff crossed roller bearings for superior performance.
Description of the XYR™ Linear Positioning Stage
The Dover XYR™ linear positioning stage features a specialized monolithic center that couples the upper and lower axes, making the stage stiff and compact and machining in orthogonality between the axes. Both motors are mounted to the center section and move with the lower axis only. Motors, knobs, couplings, Hall effect end of travel limits, and screw locking connectors are included.
There are two grades of lead screws available, commercial and precision, depending on the requirements of the application, and linear or rotary encoder feedback can be added for increased positioning accuracy. For applications where a ball screw positioning stage is preferred, see Dover Motion’s XYRB series.
Applications for this linear translation stage include semiconductor wafer placement, factory automation, medical sample motion, microelectronics assembly, inspection, and laser machining.
