Special equipment for industry

AS Tech Druckübersetzer

Pressure Intensifier

Our pressure intensifier is useable with existing hydraulic pumps from low-pressure application or from hydraulic torque wrenches application – up to 3000 bar. Connection is possible to pumps made by all manufacturers and suitable for pressure ratio up to 1:16.

AS Tech Industriehydraulik

Hydraulic systems

Our spectrum ranges from small mobile units up to stationary hydraulic systems. The operating pressures starts at 300 bar (4,350 psi) in the auxiliary hydraulics by 1000 bar (14,500 psi) in the working hydraulics up to 4000 bar (58,000 psi) in the high pressure hydraulics. It is important for us to analyze your application parameters…

AS Tech Spannwegunabhängige Ausführung mit Kontermutter

Clamping stroke independent version with locking nut

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…

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…

AS Tech Automatische Schraubenspannvorrichtung

Automatic bolt tensioner

This purely axial method allows engaging the tensioning force exactly into the connection. The optimization of assembly time is the biggest benefit. Due to the automatic bolt tensioner eliminates time-consuming screwing and unscrewing. The resulting time saving of the tensioning is approximately 50%. Standard design Patented thread clamping Drive gear, teethed nut and gearbox Automatic…

AS Tech Mehrstufige Schraubenspannvorrichtung

Multi-stage bolt tensioner with exchangeable tension nut

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…
