The VULKARDAN F is the successor of the well-established VULKARDAN E and complements the VULKAN highly flexible couplings product portfolio below the RATO R torque range. In comparison to similar couplings the VULKARDAN F is characterized by a very compact design, resulting in a weight reduction and a very short installed length. Furthermore, the optimized design of the element increases the heat dissipation considerably which results in high power loss. Accordingly, VULKARDAN F highly flexible couplings can also be installed in applications with high alternating torques, and temperature induced ageing processes are efficiently reduced.
The VULKARDAN F is suitable for flexibly mounted drive systems and makes it possible to compensate radial, axial and angular offsets by using a very soft element in combination with a high-performance membrane. The VULKARDAN F is available in four rubber qualities, as well as in silicone, enabling a perfect torsional tuning of the drive train. With its torsial highly flexible elements, the VULKARDAN F is specially designed to avoid gearbox rattling sound in small gearboxes. In addition, a modular tuning mass is available which can be attached after the installation of the coupling to achieve the highest comfort requirements.
Compact and short-build design for the smallest possible space requirements and easy handling. Vulkardan F rubber and silicone couplings achieve effective vibration protection and high displacement capacity, which guarantees the protection of connected machinery and therefore the highest system availability
Low weight for the protection of engine bearings and reduction of service costs
Optional tuning mass used for a subsequent fine-tuning and achievement of the highest possible comfort
Due to the high permanent power loss, Vulkardan F highly flexible couplings are suitable for all propulsion and generator applications
For high performing transmissions: Highest torsional flexibility for an efficient avoidance of gearbox rattling sounds especially for size F50 and smaller
Torque Range TKN [kNm]
5.20 kNm - 32.50 kNm
Speed range [1/min]
2,100.00 RPM - 2,750.00 RPM
Free standing installations especially flexibly mounted installations for main propulsion, auxiliary and power generation.
The assembly of the VULKARDAN F comes with an innovative, weight- and assembly time-saving approach. The alignment tools – three lever – properly align the coupling in an easy way even in flexible mounted engines.
