HYDRAULIC RINGS AND HYDRAULIC NUTS
GH-DI Series is used when strong torque is required mainly in confined operating spaces or for frequent disassemblies and assemblies.
• Hydraulic nuts replace the traditional hexagon nuts because they guarantee higher and controlled bolting values, they are built based on the dimensions and force values requested by the user.
Hydraulic pressure is applied simultaneously to each hydraulic nut, the force applied is a direct axial force to the bolt which generates a bolt elongation. This elongation/tension is permanently retained by screwing the locking collar of the hydraulic nut.
• They are used in the nautical, steel-making and mechanical sectors.
• Hydraulic nuts series operating pressure 2,250 bar for tension rods M36 – M56 – M72 with treated surface and special coatings for environments with high working temperatures.
• Hydraulic nuts can be made to the customer’s specifications to get the most out of the clearances available.
