1/4″x12mm Slit Beam Flexible Shaft Coupling

1/4″x12mm Slit Beam Flexible Shaft Coupling is a precision-machined, single-piece coupling designed to connect shafts while delivering zero-backlash torque transmission and balanced overall performance. Ideal for general-purpose applications, this coupling offers medium torque capacity, good misalignment tolerance, and medium torsional stiffness for reliable motion control. Its slit beam design allows it to flex under radial and angular misalignments while also providing some vibration damping, making it a strong all-round choice for motor and encoder systems. While it comes at a higher price than standard couplings, its combination of precision, flexibility, and versatility makes it a popular choice for many motion control systems. Pros and Cons Choose this coupling this coupler as an excellent all rounder. Pros Cons Medium Torque Capacity: Suitable for general-purpose applications. Good Misalignment Tolerance: Accommodates radial and angular misalignments. Medium Torsional Stiffness: Staggered slits provide good torque transmission. Zero Backlash: Provides accurate torque transmission with some compliance. Some Vibration Damping: Spring design can absorb some shock and reduces noise. Higher Price: Advanced design and performance characteristics increase cost compared to standard couplings. 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.
