Product Features
Hydraulic Nut Working Principle: Internal hydraulic pressure acts directly on the piston to apply an axial tensile force to the bolt, elongating it within its elastic deformation range. The locking nut on the hydraulic nut is then tightened to retain the required preload in the bolt.
Allows multiple bolts to be tensioned simultaneously, ensuring uniform and consistent preload around the entire bolted joint.
Standard working pressure: 150 MPa (1,500 bar).
Can be powered by electric, pneumatic, or hand-operated hydraulic pumps according to customer requirements and site conditions.
Provides a fast, accurate, and reliable method for tightening bolts, studs, and tie rods in demanding industrial applications.
Hydraulic oil ports are available in either top-entry or side-entry configurations, providing greater installation flexibility for different operating spaces.
