Hydraulic nut HFHN-15 series

HexFoce hydraulic nuts revolutionize large bolt tensioning, offering a safe, efficient, and precise solution. This nut features an internal jack with an external locking collar. Pressure creates a gap between the nut and collar due to joint compression, gasket presence (if applicable), and bolt elongation. The nut is pressurized above the desired preload, then the collar is tightened. Releasing pressure transfers the load to the collar, but some pre-load loss occurs due to collar thread settling. This loss is more significant with shorter bolts. HexForce Hydraulic Nuts: The Safe, Efficient, and Precise Way to Tension Large Bolts Transform Your Large Bolt Tensioning with HexForce Hydraulic Nuts: HexForce hydraulic nuts revolutionize the process of large bolt tensioning, offering a safer, faster, and more precise alternative to traditional methods. HexForce hydraulic nuts promote a safer work environment by utilizing controlled hydraulic pressure for accurate bolt tensioning. Applications Bearing Installation and Removal: They excel at mounting and dismounting bearings on tapered shafts or sleeves. The controlled force ensures proper seating and prevents damage to the bearings during the process. Pre-Tightening Large Bolts: Tightening massive bolts often requires significant force. Hydraulic nuts deliver this force accurately, preventing under-tightening (which can cause looseness) and over-tightening (which can damage threads). Locking Large Workpieces: These nuts are adept at securing large components together. The precise force application ensures a strong and secure connection.
