💡 Why are flexible parallel jaw couplings used in CNC and motion control systems?
Flexible jaw couplings are designed to protect precision components while maintaining accurate motion.

• Absorb angular and parallel misalignment between motor and driven shaft

• Reduce vibration and shock loads transferred to bearings and ball screws

• Maintain consistent torque transmission at varying speeds

• Improve system reliability in CNC, automation, and stepper motor drives

This coupling is a handy choice for clean, controlled power transfer in CNC and motion setups where alignment tolerance and smooth operation really matter.
