Alio Rotary Stages - PDF Catalogues
ALIO has developed ultra high precision rotary stages that meet and even exceed today's demand for high precision motion.
Mechanical Rotary Stages
The mechanical bearings rotary stages are designed with crossed roller bearings for improved stiffness for off set loads and rotational precision. This attention to materials and machining by ALIO is maintained in the rotary product line, as well as with the linear products. This is to make sure the bearings and metal are located in ultra precisely machined parallel surfaces. Note: the precision lands on the top of the AI-80R-D picture
ALIO stages have a standard 0.2 arc second resolution with the ALIO supplier motion controllers and typical standard mechanical crossed roller bearings are rated at 20 microns or radial and axial run-out with optional 6 microns also available.
Crossed Roller Bearing Goniometer
Goniometer stages are an affective solution for 5 to 10 degrees of pitch and yaw applications. The ALIO ‘gonio’ product family has several size and mass capabilities, all with precision crossed roller bearings for stiffness and precision.
Gimbal Rotational Stages
When ultra run-out precision is needed customers can choose from precision ground ceramic or air bearings and also have customised theta stages to meet demanding environment and precision needs with either of these designs.
