Overview

The SITO DRIVE HD-08 is a micro harmonic reducer offered with 30, 50, or 100 transmission-ratio options. Its 40 mm diameter, 11.5 mm thickness, ≤0.061 kg weight, and ≤20 arcsec backlash support selection for compact motion-transmission layouts. Torque ratings and allowable loads vary by the selected ratio, so choose the option to match the required input-speed and torque conditions.

Features

Micro harmonic reducer configuration.
Selectable transmission ratios: 30, 50, or 100.
Maximum allowable input speed of 8500 rpm and allowable average speed of 3500 rpm for all ratio options.
Backlash of ≤20 arcsec for all ratio options.
