💡 What is a shaft coupling used for in DIY machines?

In simple terms, a shaft coupling connects the motor output to the driven shaft, allowing for small misalignment and damping vibration while transmitting torque. Here are quick points:

• Transfers torque between motor and driven shaft with a forgiving link
• Helps absorb angular and parallel misalignment to protect bearings
• Made from aluminum for light weight and corrosion resistance
