Linear Motion Systems
ALIO Industries has focused on nano precision motion for over 10 years. During these years ALIO engineers have passionately developed products, manufacturing techniques and intellectual property (IP) for 6-D Nano Precision® in the True Nano® world. ALIO does not build legacy products or overlook the 6 dimensional errors associated with simple linear motion. ALIO designs and manufactures with these issues in focus with new unique manufacturing techniques and leading edge components then tested to NIST traceable nano results. ALIO linear products have been designed and manufactured to have no equal in the world for performance and reliability. ALIO’s mechanical bearing stages bearing stages can perform at a level of precision that the competition struggles to match with their air bearing stages. ALIO’s focus on 6-D Nano Precision® only while others design and build to the 2-D world of planar repeatability and accuracy keep ALIO on the leading edge. All of the product families of ALIO linear stages have world class performance with variation of components such as motors and encoders to fit demanding applications or cost sensitive systems.

ALIO’s NEW Asymmetric, Monolithic XY stages
These Asymmetric XY’s represent another unique ALIO offering in the industry. Over the years we’ve come across many applications that do not require identical travel lengths on both axes. A standard Monolithic XY is always what we would recommend regardless of the different X and Y travel requirements as we know a stacked XY is going to compromise performance. We would sometimes limit travel in the upper axis which would save on the overall moving footprint but the square body of the stage would still be larger than it would need to be based on the required travel for the application. Competitors very often will offer an XY stack comprised of their single axis crossed roller stages and tuning was always a challenge due to the torsional stiffness of the lower axis and the bending moments of the upper axis (kind of like trying to find stable footing on a diving board that is sitting on a tightrope!) For applications where the X and Y Travels do not need to be the same our Monolithic Asymmetric stages provide a solution with identical performance and smaller static and dynamic footprint compared with their square-body design counterparts. They also offer a lower profile than traditional XY stacks and without the tuning limitations of stacked assemblies. Our Asymmetric XY stages can provide customers with the exact travel ranges needed for their applications without the cost of excess travel that is not required and will never be used.
Precision Crossed Roller Bearing Linear Stages
ALIO' Nano Precision XY Monolithic product is a 3-plate systems with unmatched 6-D performance. With years of testing, continually improving designs and unique manufacturing protocols, the ALIO precision crossed roller bearing stages have no equal for quality and performance. Our linear stage product family, as shown below with counterbalance for Z applications, begin with 25 mm travel and go up to 400 mm of travel with motor and encoder options to fit your application needs.
XY Linear System
ALIO’s XY monolithic True Nano® motion systems performance is unequaled for 6-D Nano Precision®. With nanometer straightness and flatness you can be assured that your point precision is True Nano®. This stage family comes with enclosed or open center versions from 50mm travel to 450mm travel. Standard axis bi-directional repeatability is less than 50 nanometers with optional 10 nanometers bi-directional repeatability for demanding metrology or manufacturing needs. Stages can come with NIST traceable data assuring nano precision not just marketing data sheet optimism.
Servo Voice Coil Z Stage
Precision and compact designs for Z / lift stages have been an industry challenge that ALIO recognized and engineered a solution. Legacy designs such as wedges are compact but lack sub-micron precision in all 6 degrees freedom and linear stage with counterbalances take up space as well as making application tooling a challenge to design around. The ALIO nano-precision, air counter balanced Z lift stages solved this with voice coils and rigid precision structures that have application mounting location on all side of the precision rectangular structure. The ALIO VC Z stages are available up to 50 mm of travel with our nano precision designs and compact counterbalancing. Similar designs for longer travels are available upon request.
Linear CM Servo Motor
ALIO designed CM linear servo stages for customers that need less costly True Nano® precision. CM servo motor stages still have the ALIO 6-D precision with less linear force for smaller and lower acceleration applications. The stage family uses the precision anti-skid bearings as all other ALIO mechanical bearing products with the same 25 mm to 400 mm travel ranges.
