1-2 weeks delivery time Price incl. 19% VAT The Vetus Bullflex clutch is specially designed for optimal vibration suppression. Vibration due to torsional vibrations due to uneven engine operation, especially at low speeds, is effectively eliminated due to the flexible rubber insert. This prestressed rubber element ensures low noise, no play and no vibration when transmitting torque from the engine to the propeller. The Bullflex clutch reliably protects the gearbox from axial and radial impact, ensuring safe transmission of force under any conditions.
Another strength of the Bullflex clutch is the immaculate installation of the propeller shaft line.

1-2 weeks delivery time Price incl. 19% VAT CENTAFLEX coupling type M for flexible coupling, especially for yachts where there are many requirements for vibration attenuation. It is offered in two sizes, with a capacity of 40 hp to 80 hp (depending on the speed of the propeller shaft). For decades, thousands of these couplings have been operating reliably on motor boats and sailing yachts. The large volume rubber element provides even torque transmission. The couplings have a turning retainer, so that the vessel remains controllable even if the rubber element breaks. Torque up to 500 Nm. Type M 127 has a standard 4 "flange connection. Type M 160 has both a 4 "and a 5" connection. Yanmar types are supplied with a connecting flange of Ø25 to 30 mm.

What are the primary functions of a flexible shaft coupling in mechanical systems?
The primary functions of a flexible shaft coupling in mechanical systems include accommodating misalignment and reducing vibration between connected shafts. These couplings provide high torsional stiffness and flexibility, allowing them to handle angular, parallel, and axial misalignment while maintaining precision and minimizing backlash. For example, elastomer and flexible disc couplings are designed to absorb and isolate vibrations, protect drive components, and ensure smooth transmission of torque, making them suitable for high-speed applications and servomotors.
What types of misalignment can flexible shaft couplings accommodate in mechanical systems?
Flexible shaft couplings can accommodate various types of misalignment in mechanical systems, including angular, parallel, and axial misalignments. These couplings are designed to flex and compensate for shaft misalignment, ensuring smooth torque transmission and reducing wear on connected components. For example, R&D marine flexible couplings and twin disc couplings are made to handle significant shaft misalignment, providing zero backlash and maintaining high performance even under varying load conditions.
In what situations are flexible couplings more suitable than rigid couplings for servo motor applications?
Flexible couplings are more suitable than rigid couplings for servo motor applications when there is a need to accommodate shaft misalignment and reduce vibration. They are designed to handle torque while compensating for angular, parallel, and axial misalignments, ensuring smooth rotation and minimal friction. Flexible couplings, such as those featuring elastomer inserts or jaw configurations, provide better performance and longevity in high-rpm and dynamic environments, where rigid couplings might cause premature wear and alignment issues. For more information, contact us to discuss your application requirements and find the best shaft coupling for your needs.
What are the benefits of using elastomer inserts in flexible shaft couplings for managing shaft misalignment?
The benefits of using elastomer inserts in flexible shaft couplings for managing shaft misalignment include improved vibration damping and shock absorption, which protect the drivetrain and connected components. These inserts help flexible couplings to handle angular and parallel misalignments effectively, ensuring smooth and efficient torque transmission. Additionally, elastomer inserts make the couplings easy to install and maintain, as they provide a flexible yet durable connection between hubs of varying shaft diameters, reducing the need for frequent lubrication and inspection in various shaft applications.
