ETP-EXPRESS R is the Stainless Steel version of ETP-EXPRESS. It is available as standard for shafts 15-80 mm, with imperial sizes also available. Runout ≤ 0,02 mm. Number of mountings 200 – 800 (size dependent).
The extremely thin built-in dimensions allows for a compact design with low weight and inertia.
ETP-EXPRESS R 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 R 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.
Shaft h8 (R-15 only h7).
Hub H7.
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: 0,5 x T.
Pulsating: 0,6 x T.
Type R: Euronorm 1.4057, stainless steel, X19CrNi17-2.
** Screw: coated for a low and even friction in the threads.
Make sure the screw thread is well lubricated before each mounting. We recommend the use of Omega 58.
ETP-EXPRESS R can be delivered in more corrosion resistant stainless steel and plated with Nickel.
