Optimal Engineering Systems, Inc. (OES) offers two series of low cost, low profile, motorized ball bearing linear guide (profile rail) positioning stages. The AQ140 Series and the AQ150 Series of linear stages are available off-the-shelf in travel lengths of: 50 mm (1.969 in), 100 mm (3.937 in), 150 mm (5.905 in), 200 mm (7.874 in), 300 mm (11.811 in), 400 mm (15.748 in), 500 mm (19.685 in). These 2 µ resolution stages (achieved with a 10 micro-steps per step stepper motor driver) are ideal for: laser machining, testing, pick-and-place, inspection, sorting, wafer handling, semiconductor, assembly, metrology, and photonics in industrial, laboratory, and medical applications.

The tables, depending on length of travel, measure 120 x 120 mm (4.73 in x 4.73 in.), 150 x 150 mm (5.90 in x 5.90 in.) and 160 x160 mm (6.30 in x 6.30 in.) The AQ150 Series has top and side rail covers. Featuring a 4 mm per turn, precision 2 µ backlash lead screw, typical performance specifications of the AQ140 and AQ150 linear stages include: repeatability of 5 µ, positional accuracy 8 µ, straightness 6 µ, driving parallelism 15 µ, pitching 25 arc seconds, and deflection 25 arc seconds. 

Constructed of aluminum and black anodized, these stages can handle loads to 30 kg (66 lbs.) and 50 kg (110 lbs.). These low profile stages can easily be ordered in an XY or XYZ configuration. There is a knob on the back of the motor for manual adjustments or it can be replaced with an encoder.  An optional servo motor, encoder, and brake are also available. These compact linear stages are easily integrated into new and existing systems and are available as with complete plug-and-play systems or with a plug-in motor driver.
