Product Detail :
Features of the SA Series precision planetary reduction gears for servomotors (ServoAce)
High rigidity |
This tough construction is capable of withstanding high frequency starting and stopping. |
High accuracy |
This series features the low backlash required for accurate positioning. |
Low noise |
Quiet design is made possible by smooth torque transmission. |
High strength |
The internal gear is manufactured of steel and features a strong integrated design with the housing. The output shaft attachment flange is manufactured of tough cast-iron, offering high rigidity. |
Precise |
The planetary and sun gears undergo grinding after carburizing and quenching. Internal gears undergo highly precise broaching. Noise is 60 dB or less and backlash is 15 minutes. *Backlash is a value measured at 2% of the rated torque. |
Space saving |
The corner flange saves space for attachment. |
A rich variety of production ratios |
Single speed - 5 varieties, double speed - 6 varieties |
Easy motor installation |
The servomotor can be easily installed with bolts and after the shaft has been pressed-in, it is tightened down by bolts. |
Lubrication |
Grease for precision machinery (Maintenance-free) |
