We offer almost any desired option, from a motor adapter to an assembly that includes the motor and is ready for mounting right out of the box. Contact your Sumitomo representative for more details.
The Servo 100, Servo 6000, and Fine Cyclo reducers can withstand momentary shock loads as high as 500% of the rated torque.
Customers should never open the Fine Cyclo. The reduction stages of the FA-Series reducers are lubricated for life. Additionally, their internal components are matched in such a way that makes re-assembly very difficult for untrained personnel. If desired, customers may return Fine Cyclos to Sumitomo for grease replenishment after 5 years in order to increase service life.
