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.

• Why C-Flex?
• Performance Properties

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.

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.

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.

C-Flex Bearing Co., Inc. is a privately owned small business located in upstate New York. We have been incorporated since 1993. Under the current administration, we have been in business since 1988 however under different names. We began manufacturing turbine components for the gas turbine industry. In 1992, we generalized into basic machine shop work. In 1997, the three companies were merged into C-Flex Bearing Co., Inc. with the focus on our one product line, the frictionless bearing or pivot.
