GSD-250 | Servotak

GSD-250 Planetary Gearboxes can output up to 377 Nm (depends on ratio), and are suitable for servomotors up to 5kW. Their output bearings are allow for medium-high output loads. Thanks to synthetic oil lubrication, the gears are better lubricated, better cooled, and run more smoothly. Under extreme conditions such as very high cyclic rates, GSD-250 gearboxes are the perfect option.
