Two-stage Bolt Tensioners is a hydraulic tool mainly used for tightening and removing bolts. It is supplied with a hydraulic source through a hydraulic pump and uses the tensile force generated by the ultra-high pressure oil pump to elongate the bolt within the elastic deformation zone so that the nut can be easily loosened. Bolt tensioners are widely used in a number of fields, including petrochemical, nuclear, wind, hydropower, thermal power, marine, railway, aerospace, mining and heavy machinery.
Tensile force range: 200-6640KN.
Applicable bolts: M20-M160.
Maximum working pressure: 150MPa 1500Bar.

SL-Nut Hydraulic Nut for Slitting Machine Set

The SL-Nut Slitter Hydraulic Nut uses a simple ‘T-Handle’ to rotatte the ‘Pressure Screw to press in the ‘Pressure Piston’. At this poirt, the sealing hydraulic pressure is increased and the ‘ring
piston’ is squeezed out and used to tighten the sccrew tool (washer, tool, etc.)
