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 Einstufige Schraubenspannvorrichtung mit Gewinde im Kolben

Single-stage bolt tensioner with threaded puller

A feature of this bolt tensioner is its low profile. The single-bolt tensioning device is low-cost and thus has a short payback period. It is used in many different industrial applications.

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…
