Turbine Wheel To Shaft

close up of superbolt tensioner1600 MW (4 x 400 MW) pumped storage plant. 5 1/2" diameter studs.

Problem: Bolting of the turbine wheel to the drive shaft often requires overhead tightening. This often involves manipulation of a heavy hydraulic wrench in a confined area. Typical of large diameter fasteners, galling and seizure can occur.

Solution: Overhead work is simplified with the low torque requirement of Superbolt® Tensioners. Torques are usually below 150 ft-lbs. The tensioners are made from stainless steel to resist corrosion. Galling and seizure is eliminated.
