Super Plastic Couplings

Flexible Shaft Couplings

C-Flex couplings are designed to connect two rotating shafts, accommodating large misalignments while transmitting high torque loads with zero backlash. Their construction ensures a low moment of inertia and minimal impact on system dynamics. A large through hole allows for smaller couplings to fit larger shafts, and the ability to disassemble before installation makes them ideal for retrofit applications. These features make C-Flex couplings an efficient and versatile solution for various mechanical systems.

Durable and Reliable Construction

C-Flex couplings are constructed using high-strength hardened stainless steel or glass-impregnated polyamide flexures, ensuring no maintenance is required for years of trouble-free operation, even in contaminated environments. These couplings are directionally independent, providing the same torsional rigidity and offset capability regardless of rotation direction.

Custom Solutions

Custom Couplings For Specific Requirements

We offer custom coupling solutions tailored to your specific requirements. Whether you need unique dimensions, materials, or performance characteristics, our engineering team can design and produce couplings that meet your exact needs.

Efficient System Performance

Using C-Flex couplings in mechanical systems to connect rotating shafts reduces energy usage and bearing failure by minimizing stress on bearings. Misalignment forces generate heat, which is wasted energy, but C-Flex couplings significantly reduce these forces, resulting in a more energy-efficient system.

Superior Technology at Low Cost

C-Flex couplings offer advanced technology at an affordable price. Choosing the correct coupling for your application ensures exceptional longevity, even in the harshest environments. These couplings provide reliable performance, reducing energy usage and bearing failure, ultimately leading to a more efficient system.

Secure Clamping Options

C-Flex couplings typically come with two set screws positioned at 90 degrees for shaft clamping. Alternatively, they can be equipped with C-Flex’s patent-pending progressive clamp bushings for secure, mark-free clamping. Additionally, a collet-style shaft locking design for the lattice servo coupling is under development and will be available soon.
