Overview
The SITO DRIVE HD-11 reducer is offered with 30, 50, or 100 transmission-ratio options for robotic drive applications. Each ratio has its own torque ratings at a 2,000 r/min input speed, while the maximum allowable input speed is 8,500 rpm and allowable average speed is 3,500 rpm. All listed ratio options specify backlash of ≤20 arcsec, helping buyers select the appropriate reduction ratio and load limits.
Features
- Selectable transmission ratios: 30, 50, and 100.
- Maximum allowable input speed: 8,500 rpm; allowable average speed: 3,500 rpm.
- Specified backlash: ≤20 arcsec for all listed ratio options.
