Overview
The SITO DRIVE CS Mini-03 Reducer is available with a transmission ratio of 30 or 50 for robotic application scenarios. Both options use the CS-03-1U-U model designation and are rated for up to 10,000 rpm input speed, with an allowable average speed of 6,500 rpm. Select the ratio according to the torque values and speed-reduction requirement of the intended drive assembly.
Features
- Two selectable transmission ratios: 30 and 50.
- Maximum allowable input speed of 10,000 rpm for both ratios.
- Backlash of ≤20 arcsec for both ratios.
