ETP-TECHNO is available as standard for shafts 15-130 mm, with imperial sizes also available. Run out ≤ 0,006 mm. Number of mountings 500 – 5000 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia.
ETP-TECHNO is a hydraulic connection which consists of a double-walled hardened stainless steel sleeve filled with a pressure medium, and a flange. The flange part contains a stainless screw and piston with seals to maintain pressure.
When the pressure screw is tightened the double-walled sleeve expands uniformly against shaft and hub and creates a rigid joint. Dismantling is done by loosening the screw. ETP-TECHNO returns to its original dimensions and can easily be dismantled.
When the pressure screw is tightened to the recommended tightening torque, the piston has reached the bottom of the bore. ETP-TECHNO creates a uniform surface pressure against the shaft and hub.

Transmittable torque, T, is for static load. If the load is alternating or pulsating torque, reduce the transmittable torque, T, with the following factors: (factor x T).
Alternating: 0,7 x T.
Pulsating: 0,8 x T.
