en.Wedoany.com Reported - PI USA (PI (Physik Instrumente)) has introduced standard and custom air bearing linear slides, designed to provide ultra-smooth, frictionless linear motion solutions for precision motion control. These systems, built on years of engineering and manufacturing experience accumulated by the PI USA team in Massachusetts, achieve sub-micron straightness and flatness with zero crawling during operation.
Air bearing slides create a pressurized air film that enables non-contact suspension between moving and stationary components, resulting in near-zero friction and wear-free operation. This technology makes them suitable for demanding applications such as precision metrology, surface topography measurement, semiconductor wafer inspection and processing, optical and mechanical alignment, precision assembly, ultra-high-resolution scanning systems, optical metrology, laser technology, tribology, and research and laboratory instrumentation.
The product series offers travel ranges from 50 to 1000 mm, with nine platform sizes ranging from 50x50 mm to 300x300 mm, and load capacities up to 760 kg. Key advantages include elimination of lubrication to prevent particle generation, zero backlash and zero crawling, no mechanical wear over long-term performance, and configurability with integrated motors, linear encoders, or external drive systems.
These U.S.-manufactured passive air bearing guides can be used with manual adjustment mechanisms or integrated into automated positioning systems via linear motors or other drive technologies. PI USA's slides are available in various sizes and load capacities, are compatible with cleanroom environments, and can be customized for special environmental requirements.
PI USA also designs and manufactures motor-driven air bearing motion systems, as well as other precision motion control equipment, including direct-drive linear and rotary stages, multi-axis positioning systems, nanopositioning stages, piezoelectric actuators, hexapods, fast steering mirrors, and integrated motion subsystems. These technologies aim to provide precision motion control solutions for demanding automation, metrology, photonics, semiconductor, and research applications, offering long travel, high dynamics, frictionless motion, and nanometer-level resolution.
