Aerotech has completed and launched its low-cost Pro series linear stages. It can now offer a total of 68 standard models with travel from 50mm to 1,500mm in a choice of four stage widths from 115mm to 280mm for high-throughput, medium-precision positioning. The modular range features Aerotech's hard-cover/side-seal system that provides entire stage protection for arduous manufacturing environments such as laser machining. With high-load-capacity linear-motion guide bearings and servo-motor-driven precision ballscrews, available in normal or 'faster' pitches for speeds of more than 1.4m/s, the range is suitable for demanding multi-axis-positioning applications across manufacturing and test. The Pro series has been designed as an adaptable family of positioning stages that allow original equipment manufacturers (OEMs) and system integrators to select and mix models to match their machine-building requirements. For typical applications, the 115mm and 165mm narrow-width ...

Aerotech has launched a range of precision worm-drive rotary stages featuring large through-apertures and a preload system that provides a high level of accuracy with minimal wear. The AGR series covers five models with internal diameter from 50-200mm and is available with continuous 360deg travel, or with a mechanically limited travel range (down to 5deg). Axial load capacity is up to 570kg and rated speed to 30rpm; and the range includes optional directly mounted encoders for best performance repeatability and negligible levels of hysteresis and backlash. Typical specifications across the AGR series include a 120 arc-sec positional accuracy without encoder fitted and 20 arc-sec when the servomotor mounted encoder option is used. Corresponding without- and with- encoder specifications for bidirectional repeatability are 30 arc-sec and 8 arc-sec. Stage resolution, with a 2500 line servomotor mounted encoder fitted on the largest stage, is 2.1 arc-sec - while the same size stage wi...
