Fine Cyclo T-Series

F2C-T cylindrical housing with integrated tapered roller bearings

Double stage high-precision gearbox

Overview
Technical Info

Spur gear pre-stage and three eccentrics provide highest transmission accuracy, minimum speed ripples and minimum vibration.

With an optimized profile of the disc lobes, this exceptionally low-vibration gearbox reaches a very high transmission precision, and provides a high degree of efficiency even in the low speed range.

Less than 0.5 arcmin Lost Motion
Ideal for traverse movement applications
High input and output speeds possible
Integrated tapered roller bearings on output
Motor connection with keyway or clamping system on request
Motor adapter on request

What options are available for the precision reducers?

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.

What is the shock load capacity of the precision Cyclos?

The Servo 100, Servo 6000, and Fine Cyclo reducers can withstand momentary shock loads as high as 500% of the rated torque.

How often does the Fine Cyclo® require maintenance?

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.
