SWT/HY Series

Extremely versatile hydraulic clamping device.It can be used as a nut screw or spacer ring. For special applications the annular clamping surface can be inwardly or outwardly adapted. The pressure screws positioned secantally in the base frame allow an extremely low design. The self-contained hydraulic is actuated by the pressure screws.The axial clamping power thus generates amounts to many times being obtainable by mechanical means regardless of the mechanical prestressing. The effective clamping pressure is adjusted and monitored by what is usually a 2-stage secantal clamping pressure indicator according to the internal hydraulic pressure. The hydraulic pressure does not generate any radial force so that the parts remain in the aligned position. The hydraulically cushioned clamping surface allows a secure defined axial clamping pressure even in the e of non-parallel parts. The aids required for mechanical clampingsuch as wrench extensions and hammers are not required in the e which means a further contribution to labour saving accident prevention and reduced setup times.
