Crossed Roller Bearing Rotary Stages

ALIO Industries offers a range of precision rotary stages that are designed to meet the most demanding applications. Our standard rotary stage family uses crossed roller bearings and frameless torque motors to provide extreme throughput, acceleration, and mass capabilities while maintaining nanometer-level precision. These rotary stages are also highly stiff and can handle offset loads with ease.

Our crossed roller bearing rotary stages have +/-0.2 arc-second repeatability and are rated at 13 to 20 microns of radial and axial run-out. Some models even offer run-outs below 5 microns. We also offer mechanical bearing rotary stages in different sizes to meet varying duty cycles, mass, and acceleration needs, ranging from 80 mm to 300 mm in diameter. For mounting a vacuum chuck, vacuum rotary union options are available on the inner diameter.

Explore ALIO’s range of crossed roller bearing and mechanical bearing rotary stages to find the perfect solution for your rotary motion system needs.

Rotational Air Bearing Stages

ALIO Industries offers a line of air bearing rotary stages for manufacturers that require the highest rotational precision. These stages move without mechanical contact, resulting in frictionless and wear-free movement. ALIO’s air bearing rotary stages can minimize errors such as wobble, eccentricity, or runout to achieve near-perfect, smooth 360-degree movement even at high speeds or when mounted vertically. Equipped with powerful torque motors, these stages can perform both constant continuous rotation and step-and-settle processes with equal precision and reliability.

It’s no wonder that ALIO’s air bearing rotary stages are commonly used in highly precise applications within the semiconductor, metrology, and photonics industries. For detailed specifications, download the following spec sheets:

2 Axis Gimbal

ALIO Industries offers industry-leading torque ratings with its two-axis gimbal rotary systems, delivering high rotational speeds without sacrificing precision. The systems can be customized for each customer’s mass, with variable counterbalance, cable guidance, and cable and air feed-through capabilities. The dual-axis rotary systems allow for +/-110 and +/-170 degrees of rotation on the horizontal axis, while exhibiting angular travel +/-180 degrees for rotation about the vertical axis. An air purge is incorporated to protect against contamination and maximize lifespan.

ALIO’s 2-axis gimbal rotary systems have been utilized in a range of industries, including metrology, laser processing, and additive manufacturing. For more detailed specifications, please refer to the spec sheet.

Standard Hybrid Hexapod

At ALIO Industries, we believe that traditional hexapods will soon become obsolete. That’s why we’ve developed the Hybrid Hexapod®, a patented and revolutionary approach to six-degree-of-freedom (6-DOF) positioning that delivers nanometer-level accuracy at any working point.

Our innovative modular design features a tripod with non-contact linear driven motors and linear encoders, offering any rotary- and Z-motion capabilities on a monolithic XY basis. Unlike traditional hexapods, the Hybrid Hexapod® boasts a unique stiffness, enabling us to avoid common problems associated with screw-driven Stewart platforms, such as pitch errors, backlash, and friction.

With our design, you can move in X or Y with just one axis, tip or tilt with just three legs of the tripod, and rotate around the Z-axis by adding a 360-degree rotary stage in the middle of the tripod. These features, along with many other specific details, make the Hybrid Hexapod® an ideal solution for any application requiring 6-DOF positioning with nanometer/arc-sec levels of incremental motion and repeatability.

If you’re looking for a unique design that can simplify your six-dimensional motion while drastically increasing your working cubic volume, turn to the Hybrid Hexapod® from ALIO Industries. To learn more about our standard configurations and what they can achieve, check out our comprehensive datasheet.


MINI Hybrid Hexapod

Looking for a compact yet high-performing solution for your six degrees of freedom (6-DOF) positioning needs? Look no further than the MINI Hybrid Hexapod® from ALIO Industries.
