1/4″x8mm Curved Jaw Flexible Shaft Coupling
High torque with vibration damping and electrical isolation. Ideal for general purpose drives where shock absorption and quiet operation are important.
1/4″x8mm Curved Jaw Flexible Shaft Coupling is a three-piece coupling designed to connect shafts while providing high torque capacity, good vibration damping, and electrical isolation. Ideal for general-purpose drive and automation applications, this coupling features an elastomeric spider that absorbs shock and reduces noise during operation. Its curved jaw design delivers reliable torque transmission in demanding systems where damping and torque capacity are important. While it has low misalignment tolerance and low torsional stiffness, and the spider can wear over time, its strength and damping characteristics 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.
