SFE210 Friction Drive Equatorial Mount Designed Specifically for Fixed Observatories

The SFE210 is engineered for fixed observatories, equipped with high-resolution, low-vibration stepper motors, offering exceptionally low drift rates and a payload capacity of 40 kg.

It integrates high rigidity, low vibration characteristics, and zero-backlash transmission technology, ensuring outstanding performance during long observation sessions and under heavy operational loads.

Key Features:

1. High-Precision Control

The SFE210 utilizes specially tuned 0.9° low-vibration stepper motors. With a reduction system in place, its P-P error is better than 0.3 arcseconds, delivering stable torque and ultra-smooth power output.

2. Zero-Backlash Transmission

The SFE210 employs friction drive technology to achieve zero-backlash performance, significantly enhancing operational smoothness and responsiveness. The RA axis features a two-stage friction reduction system with a 588:1 ratio, while the DEC axis combines an efficient harmonic reducer with a synchronous belt drive system. Even under heavy loads, the device maintains high precision control and smooth responsiveness.

3. High Payload and Rigidity

Equipped with large friction disks and constructed using high-strength metal materials, the SFE210 ensures exceptional rigidity and compressive strength under heavy loads, supporting apertures up to 14 inches. For high-load operations, users can optimize load adaptability through pre-pressure adjustments, ensuring stability in various observation scenarios.

4. Ultra-Low Drift Rate

The SFE210 features a pure two-stage friction drive system. When the polar axis is aligned to within 30", it enables unguided tracking for over 2 minutes.

5. Sealing and Dust Protection

The friction drive components of the SFE210 are fully enclosed within a protective shell, effectively preventing dust and moisture from entering.
