Coupling replacement is a common maintenance task in industrial settings where machinery needs to be kept running smoothly. A coupling is a device that connects two shafts or other mechanical components together, allowing power to transfer from one part to another (like connecting a motor to a pump). When these parts wear out or break, they need to be replaced to prevent equipment failure. This task is similar to replacing a connector that joins two pieces of equipment together. Maintenance technicians who perform coupling replacements help keep industrial machinery running efficiently and prevent costly breakdowns.
