The hydraulic nut consists essentially of an internally and externally threaded piston, a cylinder and a locking nut. The hydraulic nut will be pressurized up to the desired pre tensioning force. This creates a gap between the locking nut and cylinder corresponding to the elongation and compression of the components. The locking nut will be…

Qur electro-hydraulic power units have been developed for all common hydraulic torque wrenches. The units are ideally suited for continuous operation thanks to active recirculation cooling. Due to the compact and ergonomic design including support frame, a safe and comfortable screwing ist possible. Standard design Supply voltage 90-264 V / 47-63 Hz Pressure 700 bar…

The multi-stage bolt tensioner with exchangeable tension nut is used to generate high prestressing forces using small outside diameter. This tool is mainly used in the field of turbines, large bearings and pumps. Also in many different industrial applications. Standard design Hydraulic body with turnable, fixed support sleeve Drive gear, teethed nut and gearbox Automatic…
