💡 What is a shaft coupling commonly used for?

These handy parts join rotating shafts and help manage misalignment in small machines.

• Transmit torque from motor to driven shaft
• Compensate minor angular and parallel misalignment
• Reduce vibration to protect bearings and gears
• Ideal for stepper motors, 3D printers, CNC tools
