8x10mm Helical Beam Flexible Shaft Coupling

8x10mm Helical Beam Flexible Shaft Coupling is a precision-machined, single-piece coupling designed to connect shafts while compensating for misalignment. Ideal for cost-effective light to medium-duty applications, this coupling uses a helical cut design that accommodates radial and angular misalignments while also providing some vibration damping. Easy to install and maintain, it is commonly used in stepper motor and encoder setups where flexibility and simplicity are important. While it has low to medium torque capacity and low torsional stiffness, its misalignment tolerance and economical design make it a popular choice for many motion control systems. Pros and Cons Choose this coupling for cost effective applications with shaft misalignments. Pros Cons Good Misalignment Tolerance: Accommodates radial and high angular misalignments. Some Vibration Damping: Spring design can absorb some shock and reduces noise. Low to Medium Torque Capacity: Not ideal for heavy-duty applications. Low Torsional Stiffness: Can introduce spring-like behaviour in high-precision 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.
