Fine Cyclo B Series: The Next Generation of Cyclo Precision Gearboxes

Compact in diameter. Big on performance.

The Fine Cyclo B series combines a compact design with maximum precision and high-power density. The newly developed series featuring Cyclo technology covers outer diameters from 120 to 231 millimetres and transmits acceleration torques from 417 to 4,000 Newton-metres; in the overload range, it can withstand peak torques of up to 8,000 Newton-metres during emergency stops.
Axial and radial runout in the micrometre range, high torsional rigidity and maximum transmission accuracy ensure precise and dynamic movements even under the most demanding conditions.
Thanks to its single-stage design and wide reduction ratio range (29–179:1), the B Series can be integrated into machines in a particularly space-saving manner. The modular drive system also ensures quick and standardised adaptation to various motor and interface concepts.

The series comprises two versions that cover different requirements:

• F4C-B “main bearing type” – plug-and-play gearheads for robust precision axes
The F4C-B variant with integrated main bearing impresses with exceptionally high rigidity, peak torque capacity and precise transmission accuracy – completely free of mechanical backlash.

• FC-B “KIT type” – Modular precision gearbox for customised machine solutions
The gearbox kit offers maximum design freedom for customised machine concepts. It focuses on the core function of precise torque transmission and enables application-specific design – particularly where integration and interfaces are defined individually by the customer.
