Product overview

ALIO has introduced its new Micron 2 (µII) motion systems family to compete in the micron-level motion control market, where the demand is for low-cost, mid-precision, reliable, long travel stages. As with all ALIO’s Micron 2 (µII) motion systems are designed using the company’s uncompromising standards of “quality first” thereby ensuring long-term reliable operation.

The Micron 2 (µII) recirculating ball rail bearing stages come as standard in sizes of 100mm up to 2 meter thus providing the end-user a solution for a large variety of applications. The Micron 2 (µII) motion systems family is a robust, powerful line that is designed to be used either stand-alone, or as a top axis of an integrated solution.

Standard, Dual Ball Rail Micron 2 X Stages

Combining linear direct drives with dual recirculating ball rails instead of crossed roller bearings opens up the precision world to many more applications and customers.

This robust system architecture helps customers to overcome budget-constraints as they move towards micron to nano precision, and exceeds the travel possible using crossed roller bearings.

The nine standard stages of this series allow flexible travel ranges from 100mm to 700mm. By strictly adhering to ALIO’s design and manufacturing principles they can be used not only when mounted on a flat horizontal surface, but also when used on vertical surfaces or even inverted.

High flex cabling with optimized routing, hard stops, high resolution encoders, optical latching home index, and end-of-travel Limits, etc… are designed with a total focus on the production of highly robust and precise motion with an economical price tag to help industrial and heavy duty applications get to the next level of precision.

Take a closer look in the datasheet:

Slim, Single Ball Rail X Stages

Our two lines of “Slim” Micron 2 (µII) motion systems utilize recirculating ball rail bearings together with linear direct drives. The stages either come in a compact housing or as “naked” version. Both versions are ideal as a basis for more complex systems, and are widely used in Cartesian Gantry systems.

Wherever long travel ranges of up to 1m are required but space matters, these lines are probably your best choice. No matter which of the many standard lengths you choose, a 72 mm width and a height of just 57mm mean that you don’t need to make compromises: as precise as a +/-0.5µm bi-directional repeatability is guaranteed!

ALIO’s proprietary design and manufacturing process used in these two Micron 2 (µII) lines help achieve surprisingly good flatness and straightness.

Extra Large Ball Rail X Stages

These three series of products are designed for extreme applications. They can carry heavy, large objects, targets, and products and can be used over extra-long ranges. Equipped with dual recirculating bail rail bearings, driven by a linear direct drive, these robust stages can reach lengths of up to 2m on which with carrier plates up to 300mm wide and either 170mm, 270mm or even 306mm long.

It is therefore not surprising that all these stage can carry payloads of up to 100kg and achieve acceleration of 2.0 G -4.0 G.

What is perhaps more surprising, however,  is that customers can still expect a bi-directional repeatability of less than +/-0.5µm and 1-digit micron and arc-sec in flatness, straightness, pitch, yaw and roll.

All details can be found on the datasheets:

High-Force, Payload and Range – Ball Screw Driven X Stages

For certain applications, an electromagnetic linear direct drive might not be ideal. This is specifically true for applications that require the ability to hold position (literally no movement on power loss) even during a sudden or necessary power stop or loss. This is often critical when high payloads (but not only high payloads) are involved, or if a stage needs to be mounted other than horizontally.

ALIO has therefore extended its range of stages suitable for these kinds of challenges with further Micron 2 (µII) motion systems. Those stages known as the “SBS” and “XBS” series use a frameless torque motor that drives the carrier with a precision ball screw on dual recirculating ball rail bearings. For further strength, certain stages can be equipped with brake options contributing to the safety of the machines.

Even with this combination of drive and bearings, the stage will successfully accomplish applications requiring a bi-directional repeatability of only +/-1 µm. The ball screws anti-backlash nut ensures any backlash is avoided.

Micron 2 Rotary Stages

ALIO’s Micron 2 Rotary Stages utilize frameless torque motors and angular contact, duplex pair bearings. These stages are designed to achieve maximum possible throughput without compromising on precision, regardless of whether the application requires a smooth, continuous movement or a fast step and settle process. Also allowing decent sized apertures, those rotational stages are used in a broad selection of applications and industries such as industrial manufacturing, photonics or semiconductor metrology.
