Hydraulic nuts series DI

FPT – Fluid Power Technology is a manufacturer of hydraulic nuts, a product that replaces the existing hexagonal nuts to provide a punctual and uniform load at each bolted joint. They allow the tensioning of large diameter bolts with ease and with high and precise preloads. The tightening operation is carried out in narrow spaces and it is possible to eliminate the torsional stresses due to the damage to the thread. They can have upper or lower clamping collar, they are extremely compact, moreover it is possible to connect together any number of hydraulic nuts for simultaneous operation, guaranteeing uniform tensioning. They are used in all those applications where it is not possible to use a mechanical nut due to the need for continuous maintenance operations, for high temperatures or strong vibrations. The typical application is for the tightening of the columns of the presses, of the mining machinery and other mechanical applications. The hydraulic nuts can have various threads, forces, pressures and dimensions based on specific project requirements. Very high pressure hand pumps, electric or air hyadraulic pumps from 700 bar up to 3000 bar can compose and operate the hydraulic system.
