• Maximum flow rate: 3 - 28 cm³/s

This hydraulic swing clamp is a pull-type cylinder where a part of the total stroke is used to swing the piston. It is used for the clamping of workpieces, when it is essential to keep the clamping area free of straps and clamping components for unrestricted workpiece loading and unloading.

ROEMHELD B1.943 Threaded Body Work Supports 3 function types, with metallic wiper edge, optional contact control single acting

• Maximum operating pressure 500 bar
• External thread: M30 - M60

The support plunger is hydraulically extended by a small piston and contacts the workpiece with spring force. The pressure can be easily exchanged. Locking of the support plunger through the slotted clamping sleeve is made by means of a ring-shaped conical hydraulic piston where the locking force is transmitted by a low friction ball shell. Unlocking and retracting of the support plunger is made by spring force.
