AS Tech Spannwegabhängige Ausführung mit Passblech

Clamping stroke dependent version with spacer plate

The hydraulic nut consists essentially of an internally threaded cylinder, a piston and a splitted spacer plate. The hydraulic nut will be pressurized up to the desired pre-tensioning force. This creates a gap between the piston and cylinder corresponding to the elongation and compression of the components. In this calculated gap the corresponding spacer plate…
