Our custom steam turbine slot nuts are critical fastening components designed for turbine rotors, valve spindles, main steam valves, bearing assemblies, and high-pressure flanges. Manufactured from high-strength heat-resistant alloy steel using full CNC precision machining, these slot nuts are custom-made according to customer drawings, turbine parameters, and on-site operating conditions.
Featuring evenly distributed radial slots, they enable reliable locking after torque tightening, effectively preventing loosening caused by high-temperature creep, vibration, and alternating steam loads during long-term turbine operation. These components secure shaft elements, valve core parts, and rotor assemblies tightly, preventing equipment shifting, steam leakage, and unexpected unit shutdowns.
