Optimal Engineering Systems, Inc. (OES) offers a high precision series of low cost, low profile motorized single axis positioning stages.  The compact AQ110 Series of four cross roller linear stages have travel lengths of 15 mm (0.590 in), 30 mm (1.181 in), 50 mm (1.968 in), and 75 mm (2.952 in).  Open loop repeatability of all stages is 0.5μ using a 10 mirco- steps-per-step Step Motor Driver or just 0.25μ using a 20 mirco-steps-per-step Step Motor Driver.  Precision ground lead screws with just 2μ of backlash and high precision cross roller linear travel guides assures repeatability of 5μ, and positional accuracy of 10μ.

Table sizes and loads of these linear stages are: AQ110-15 is 65 mm x 65 mm (2.559 in x 2.559 in) and 10 kg (22 lbs), AQ110-30 is 90 mm x 90 mm (3.543 in x 3.543 in) and 15 kg (33 lbs), AQ110-50 is 90 mm x 110 mm (3.543 in x 4.331 in) and 15 kg (33 lbs), and the AQ110-75 is 90 mm x 110 mm (3.543 in x 4.331 in) and 20 kg (44 lbs).  Each of the tables has a pattern of 16 threaded mounting holes for the addition of custom tooling and the base has drilled and countersunk holes, for easy integration into new and existing applications.

There is a knob on the back of the motor for manual adjustments or it can be replaced with an incremental encoder. Options include: Servo motors, encoders, limit switches, and fully compatible multi-axis motion controllers.  Additionally, any of AQ110 series of linear positioning stages can be ordered as a complete plug-and-play system.
