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. Pressure pieces are replaceable.

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.
