Design: Double-acting centring clamp with two clamping points. All components from high-grade hardened and nitrided steel. Oil supply via oil channel in fixture body. Application: For centring and clamping workpieces with machined or cast holes, cutouts or penetrations. Element screwed directly onto the fixture body, sealed with O-ring. Features: The centring clamp is fastened from below; oil is supplied through drilled channels in the fixture body. If the centring clamp is fastened from above and oil supplied through conduits drilled in the fixture body, a connection plate for O-ring connection is needed. If the centring clamp is fastened from above and oil supplied through pipes, a connection plate for pipe connection is needed. Note: The practical combination of 2-point and 3-point elements can avoid over-determined clamping states. Unsuitable for use on lathes. On request: Other sizes available on request.
