💡 What is a shaft coupling used for in machinery? Shaft couplings transmit rotation between motor shafts and rods in many setups. - They maintain alignment in 3D printers and RC vehicles. - Brass material resists rust while handling steady torque loads. - The 5mm to 8mm bore range works with common motor and rod sizes. - Five pack includes screws and wrenches for quick installs.
