Hydraulic Nut

Hydraulic nuts, such as the SL-HYDNUT hydraulic nut and fractional thread hydraulic nuts, are innovative tools used in heavy-duty applications to facilitate the precise and efficient tightening or loosening of large bolts and studs. These nuts utilize hydraulic pressure to generate a controlled force, allowing for accurate positioning and alignment during assembly or disassembly processes. The SL-HYDNUT model, in particular, is known for its reliability and ease of use, making it a preferred choice in industries requiring high torque applications. Fractional thread hydraulic nuts, on the other hand, offer compatibility with fractional thread sizes, providing versatility for a wide range of fastening needs.

SL-CM Coal Mining Machine Hydraulic Nuts

The coal machine hydraulic nut utilizes hydraulic pressure to provide ultra-high preload, ensuring secure, vibration-resistant connections in coal mining equipment and other heavy industries.

SL-HN Hydraulic Nuts for Upper Loads

Hydraulic nuts for upper loads can be set to a precise preload with an accuracy of up to 3% earth; they can be supplied with a stroke indicator that allows the amount of tension to be observed, measured and controlled during operation.

SL-HN series top load hydraulic nuts are especially suitable for tightening in narrow spaces and heavy duty vibrating machinery, and can be assembled with several bolts at the same time. The torque-free design avoids friction, bolt twisting and other factors affecting bolt preload, and the tightened bolt is subjected to pure tensile force.
