ETP-EXPRESS is available as standard for shafts 15mm -100 mm, with imperial sizes also available. Runout ≤ 0,02 mm. Number of mountings 500 – 2000 (size dependent). The extremely compact design delivers low weight and inertia. ETP-EXPRESS 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 activating piston with quality seals to maintain pressure.
ETP-EXPRESS is available as standard for shafts 15-100 mm, with imperial sizes also available. Runout ≤ 0,02 mm. Number of mountings 500 – 2000 (size dependent). The extremely thin built-in dimensions allows for a compact design with low weight and inertia.
ETP-EXPRESS 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-EXPRESS 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-EXPRESS R has created a uniform surface pressure against the shaft and hub.
