💡 What is the function of a jaw-style spider shaft coupler in motion control systems?

In short, it connects driving and driven shafts while absorbing small misalignment and dampening vibration to extend equipment life.

• Torque transmission between shafts with minimal backlash
• Suitable for servo motors, stepper motors, and encoder-driven axes
• Reduces shock and noise for smoother CNC and 3D printer operation
