1/4″x8mm Disc Flexible Shaft Coupling
High stiffness, zero backlash coupling with good misalignment tolerance. Ideal for precision motion systems requiring accurate torque transmission.
1/4″x8mm Disc Flexible Shaft Coupling is a high-performance coupling designed to connect shafts while delivering precise, zero-backlash torque transmission. Ideal for high-precision motion control applications, this coupling features rigid metal discs that provide high torsional stiffness. Its disc design accommodates shaft misalignment while maintaining consistent torque transfer, making it suitable for applications where precision is critical. While it offers low to medium torque capacity and limited vibration damping, its stiffness, accuracy, and zero-backlash performance make it a popular choice for many motion control systems.

Application
Shaft couplings are widely used to connect stepper motors, servos, encoders, linear actuators, and other drive components in automation and motion systems. They provide reliable torque transmission while accommodating varying degrees of misalignment, helping maintain precision and protecting connected equipment. Common in CNC machinery, linear actuators, 3D printers, and modular extrusion-based systems, couplers play a vital role in ensuring smooth, accurate, and long-lasting operation across a broad range of mechanical assemblies.
