Aerotech ASR1300 Mechanical-Bearing Direct-Drive Rotary Collet Stage

The ASR1300 boasts significantly higher acceleration capability due to a

complete system-level optimization of torque-to-inertia ratio. As a result,

the ASR1300 is supremely agile and yet comes in a reduced package size

and weight to maintain high-throughput on supporting motion equipment.

The ASR1300 maintains all of the “out-of-the-box” material handling

capability of the ASR1100 and ASR1200.

Design Features

• Accepts tube diameters from 0.1 mm to 4 mm – new

• Compatible with Type-D collets

• Minimal collet runout – less than 25 µm TIR

• Optimized for maximum acceleration

• Features a clear, through-bore aperture & guide system for tube feedthrough

• Ultra-compact, lightweight design simplifies integration & improves throughput

• Available with optional water cooling for maximum throughput

Key Applications

The ASR1300 is the lightest, fastest and most capable direct-drive rotary collet

stage available. It’s ideal for the high-throughput manufacturing of medical

devices and tubular products, such as:

• Coronary stents

• Peripheral vascular stents

• Neurovascular stents

• Hypotubes

• Coronary microcatheters

• Guidewires

Tube Processing with Extreme Speed & Precision

Engineered and optimized for high-throughput tubular processing applications,

ASR1300 is the fastest and most capable rotary collet stage available. Now able

to accept tubes with up to 4 mm outer diameter, ASR1300 accommodates Levin

Type-D dead-length collets—so your workpiece has virtually zero axial motion

when the collet opens and closes. This helps to reduce errors in the laser-cutting

of stents, hypotubes, catheters and similar devices. ASR1300 is available with

high speed balancing allowing a maximum rated speed of 3000 rpm. With its

high-torque, low-inertia design, it can accelerate from zero to 1500 rpm over a

mere 90 degrees of travel, making ASR1300 considerably faster and more suitable

than a spindle for tubular processing. Plus, ASR1300 is our lightest and most

compact rotary collet stage, so it’s ideal for integrating with high-throughput tube

processing machines.

Integral Collet Design

The ASR1300 comes with a D-style/Levin collet chuck. These collets are readily

available in multiple sizes supporting tube diameters from 0.1 mm to 2.0 mm.

They also provide outstanding run-out characteristics for those applications

requiring high-precision gripping of tubular material. Applying air pressure adjusts

the collet from fully open to fully closed. Air is delivered to the rotating collet

assembly through a custom-designed frictionless, seal-less rotary union. 

This 100% noncontact union ensures a lifetime of maintenance-free operation.

Throughput Optimized Design

The ASR1300 has been designed from the ground up with agility in mind. An ultra

-high torque-to-inertia ratio, a unique combination collet chuck and rotary union

design, and Aerotech’s renowned precision manufacturing allow for a remarkable

8000 rad/s2 acceleration. This equates to reaching over 1500 rpm in just 90° of

travel, making the ASR1300 perfect for the most demanding tube handling

applications or any rotary-based manufacturing process where throughput is key.

Reduce your overall part cost by producing more parts per minute.

Compact Packaging

The ASR1300 is the smallest member of the ASR family. In addition to being the

fastest ASR rotary stage, it weighs a mere 2.8 kg, less than 60% of the weight

of the ASR1100. Minimizing the weight and package size of the ASR1300 allows

any multi-axis system carrying the rotary stage to accelerate faster with less

dynamic error, allowing for further improvement to your process output.
