F2C-T cylindrical housing with integrated tapered roller bearings

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
