Proper Maintenance of Bolted Connections in Heavy Machinery

Keywords: Bolt maintenance, retorquing, industrial machinery

Bolted connections in presses, crushers, or turbines are under constant stress. A proactive maintenance schedule is essential. This includes periodic visual inspections for cracks or corrosion, and most importantly, retorquing. Initial settlement or vibration can cause preload loss. Following the manufacturer’s schedule for checking and retightening high-strength bolts with a calibrated torque wrench prevents catastrophic joint failure and extends equipment life.
