Product overview

ALIO Industries has also developed TRUE NANO® precision rotary stages to meet and exceed today’s demand for high precision rotary motion. ALIO’s line of rotary stages continues to expand as the company works with each individual customer on a one-to-one basis to provide customized motion control solutions perfectly aligned to the specifics of particular applications.

Crossed Roller Bearing Rotary Stages

ALIO’s mechanical bearing rotary stages have been designed with crossed roller bearings for improved stiffness for offset loads and rotational precision. Integrated with servo torque frameless motors, these stages can handle applications where the mass and acceleration needs are extreme, while still maintaining nanometer-level precision performance.

Standard ALIO rotary stages have 0.2 arc-second repeatability. Standard mechanical crossed roller bearings are rated at 13 to 20 microns of radial and axial run-out, with optional run-outs of certain models below 5 microns. The mechanical bearing rotary stage family has multiple motor sizes to meet duty cycles as well as mass and acceleration needs from 80 mm to 300 mm in diameter. Vacuum rotary union options are available on the inner diameter for mounting a vacuum chuck.

360 Degree Angular Contact Bearing Stages

ALIO has designed mechanical bearing rotary stages with angular contact bearings representing the most compact design on the market. Integrated with servo ironless motors, these stages best fit metrology applications where small angular adjustment is needed with nanometer-level precision performance.

Rotational Air Bearing Stages

When ultra-tight run-out precision motion is needed, manufacturers can choose from ALIO’s continually growing line of air bearing rotary stages. Whether it is exceptional stiffness or cost-effective motion that is the priority, ALIO Industries can offer a variety of options to meet the needs of today’s nanometer-level -precision applications.

2 Axis Gimbal

Incorporating ALIO’s industry-leading torque ratings, out two-axis gimbal rotary systems are capable of high rotational speeds while maintaining the stand-out precision levels expected from ALIO’s systems. Metrology, laser processing, additive manufacturing, and many other industry sectors have benefited from these ALIO products., and air purge is incorporated for contaminant protection and longer life.  Internal cable and air- line routing provide an extremely clean finished product.

ALIO’s two-axis systems are designed around the customers’ mass with variable counterbalance, cable guidance, and cable and air feed-through capabilities.  With hard-stops allowing for ± 110 and ± 170 degrees of rotation for nearly unlimited part access on the horizontal axis, ALIO’s dual axis rotary systems exhibit angular travel ± 180 for the rotation about the vertical axis.

Open-Center Rotary Stages

ALIO’s large open-center rotary stages utilize a tangential linear direct drive with angular contact (duplex pair)
bearings. This low-profile design is suitable for high-throughput
applications requiring up to +/- 7.5 degree angular movement and an extreme aperture for maximum accessibility from both sides.
