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.

Benefits
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
