Fine Cyclo T-Series
Double stage high-precision gearbox
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
Variants:
- F2C-T cylindrical housing
- F2CF-T flange housing

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.
