Linear guide stages
Van Nuys, California – Optimal Engineering Systems, Inc. (OES) offers two series of 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 50mm (1.969"), 100mm (3.937"), 150mm (5.905"), 200mm (7.87"), 300mm (11.811"), 400mm (15.748"), and 500mm (19.685"). These 2µm resolution stages (achieved with 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 120mm x 120mm (4.73" x 4.73"), 150 x 150mm (5.90" x 5.90"), and 160mm x 160mm (6.30" x 6.30"). The AQ150 Series has top and side rail covers. Featuring a 4mm per-turn, precision 2µm backlash lead screw, typical performance specifications of the AQ140 and AQ150 linear stages include repeatability of 5µm, positional accuracy 8µm, straightness 6µm, driving parallelism 15µm, pitching 25 arc seconds, and deflection 25 arc seconds.
Constructed of aluminum and black anodized, these stages can handle loads of 30kg (66 lb) and 50kg (110 lb). 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 with complete plug-and-play systems or with a plug-in motor driver.
