# Rotary Stages

![rotary stages](https://precisioneersgroup.com/wp-content/uploads/2026/02/Rotary-Stage-Composite-600x480-75L.webp)

Precision rotary stages are often used for exact positioning in the manufacturing of fine electronics and medical supplies, and photonics.  Besides fine positioning, they are often utilized in machining operations such as milling, drilling, and grinding.

These rotary stages deliver backlash free, sub-micron positioning and 6.6 Nm to 127 Nm torque in compact 120 mm to 240 mm footprints.  There are hollow-center variants and modular encoders for effortless integration into multi-axis assemblies. Custom stages can be created to adapt to your modular platform to meet your torque, speed and accuracy targets.

These stages use ECOVARIO or ECOMODUL amplifiers that are CANopen and EtherCAT compatible.   [Click here to learn more about precision long & short travel integrated systems that use EtherCAT.](https://precisioneersgroup.com/nanometer-positioning-solutions/)**Two example EtherCAT compatible servo amplifiers are detailed at the bottom of this page.**

## Rotary Stage Featured Models are below.  Additional Models & Custom Systems are available.

**Small Torque Rotary HRT-105 Stages**

These small torque stages are mechanically and electrically ready to install:

- Highest torque density
- Low clogging value
- No backlash
- Integrated measuring system
- Customer specific modifications available

The HRT-105 rotary stage series is supplied as a fully wired, ready-to-connect unit complete with a direct-drive torque motor, precision rolling bearing and an incremental or absolute encoder of your choice. Its compact housing measures 120 mm in diameter. A fixed 10 mm hollow shaft lets you route air lines, fibre optics or cables cleanly through the axis, reducing external drag chains and simplifying machine layouts.

Typical use cases include high-speed pick-and-place heads, micro-dispensing stations, laser structuring platforms and precision inspection fixtures where zero backlash and sub-micron repeatability are critical.
