Tensioning nut

Hydraulic nut replaces the nut normally used and stays with the stud. It is the most compact system and does not require additional stud length. The operator simply screws the hydraulic nut down tight and connects the hydraulic hoses. After reaching pressure, he either screws down a collar (style illustrated) or inserts shims designed for the specific hydraulic nut application.

 

 

Features

1.Suitable for confined area and tightness of vibration machineries of heavy load.

2.It can  simultaneously assemble several blots of same size.

3.No torque design to avoid friction and bolt distortion and such factors that influence the pretension force of blots undergopure tensile force.

4.Precisely preload with its accuracy is as high as 3%.

5.A stroke indicator allows observing ,measuring and controlling the stroke of piston in operation.
