The axial tensioner ETP-UNIGRIP is used when workpieces or tools, for example circular knives with spacers, are going to be clamped axially against a shoulder on the shaft in an accurate position.


Hydraulic unit with two clamping systems consisting of a hardened steelbody with an inner sleeve, three axial pistons with seals and two pressure screws.


When the first screw (marked R) is tightened the inner sleeve grips the shaft, locking ETP-UNIGRIP in position. As the second screw (marked A) is tightened, the axial pistons move into contact with the component which is to be clamped. The hydraulic principle means that the axial force is evenly distributed between the three pistons, offering accurate clamping of components.


For standard sizes see leaflet.
ETP-UNIGRIP can also be manufactured with a threaded bore without hydraulic expansion of the thread, with more pistons, higher axial thrust force and longer piston stroke. It can also be made to other dimensions on request. Send your application details and we will offer you the solution.
