Support pin with internal thread case hardened and ground. Wiper to protect against dirt and cooling water. Internal parts from stainless steel. Oil supply via oil channel in fixture body. Application: The support element is used as an extra support to prevent sagging and vibration of a workpiece. Also confirms the presence of a workpiece, also on uneven surfaces such as castings. Features: The piston is retracted into its basic position while an air flow passes through the support element. When pressure is applied, the support pin advances with a weak spring-applied force against the inserted workpiece. This closes the integrated air valve to indicate that the workpiece is present and is in contact. The maximum air operating pressure is 1 bar. Then the support pin is clamped hydraulically. When the pressure is released, the support pin returns to the normal position. Very high repeatability ensures optimum production quality. Element with high load capacity and low height. Note: Support pin must be protected against the entry of dirt and splash water by fitting a set screw or plug. When placing into operation, ensure that all air is bled from the system. Failure to do so can cause destruction of the clamping element by the escaping diesel effect. To be able to absorb machining forces, the supporting force should be matched to the clamping force. The supporting force should always be at least twice as high as the clamping force. Installation dimensions: Article no. G H K N dia. P ØR dia. S dia.
