The Upper Load Hydraulic Nut is a hydraulic nut specially designed for tightening in confined spaces and in heavily loaded vibrating machinery. It has a torque-free design that avoids the effects of friction and bolt twisting on the bolt preload, ensuring that the bolt is subjected to pure tensile force. This design allows the top load hydraulic nut to set the preload precisely with an accuracy of ±3%.
Main features
For confined spaces and heavy-duty vibratory machinery:
the top load hydraulic nut is particularly suitable for these environments as it provides a strong tightening force in a limited space.
Torque-free design:
Avoiding friction and bolt twisting ensures that the bolt is subjected to pure tensile forces, thus increasing the tightening effect.
Precisely set preload:
preload is set with an accuracy of ±3%, ensuring consistent and reliable tightening results.
with stroke indicator:
the amount of tension can be observed, measured and controlled during operation, ensuring precise control.
Suitable for a wide range of bolt sizes:
multiple bolts can be assembled at the same time, improving work efficiency.
working process
- Tighten the hydraulic nut to the upper end of the bolt being tightened.
- The bolt is stretched when hydraulic pressure is applied to lift the piston.
- Screw the locking ring against the nut body, remove the pressure and the job is done.
- The clearance at this point is the amount of stretching of the bolt.
- Power:198-2450KN
- Applicable bolts:M22-M 100
- Maximum working pressure:1500Bar
The SOLY HN Hydraulic Nuts for Upper Loads are precision-engineered to solve the complex problem of securing high-torque bolts under extreme pressure conditions. These hydraulic nuts are designed to apply consistent, controlled force, ensuring that upper-load components remain safely fastened, even under dynamic operational stresses. They are particularly useful in industries like heavy machinery, wind turbines, and power plants.
Application Scenarios
The upper load bearing hydraulic nut is widely used in occasions where frequent bolt removal is required, pre-tightening of oversized bolts and locking of large workpieces. It is especially suitable for metallurgy, copper and aluminium metal industry, paper making industry as well as the installation and dismantling of large machinery and equipment such as coal mining machines, train wheels, couplings, flywheels and gears.
Problem-Solving Capabilities:
The SOLY HN Hydraulic Nuts offer a simple yet effective solution to the challenges of bolting high-load systems. Unlike traditional mechanical methods, these hydraulic nuts allow for precise tensioning, minimizing the risk of over-tightening or under-tightening.
