The large aperture having a diameter of 120 mm is particularly significant for the rotation stages PRS-200. The body is fabricated from a high-rigidity, special, tempered aluminum alloy. Two calibrated preloaded zero backlash precision roller bearings guarantee an excellent flatness and smooth motion.
A ground and hardened screw worm integrated with a calibrated worm gear guarantee a quiet and smooth motion. As an alternative, the PRS-200 stages can be delivered with an integrated optical angular scale.
The rotation stages PRS-200 have two reference switches which can be easily adjusted by the customer. Drive variations including DC or 2-phase stepper motors are available.
The key features of the PRS-200 are:
- Uni-directional repeatability down to 0.0003 °
- Maximum speed 150 °/sec
- Load capacity up to 50 kg
- Integrated reference switches
- Optionally: angular scale
- Clear aperture 120 mm
- Preloaded worm drive for zero backlash
