High concentricity re-usable hub to shaft connections
ETP-Techno is specially designed for applications where high precision together with frequent changes and adjustments are needed. It gives very high concentricity and can be mounted/dismounted thousands of times. Shaft sizes are 15 to 100mm.
Design: ETP-Techno is made up of a double wall, hardened steel sleeve filled with a pressure medium and a flange part. In the flange there is a press/pressure mechanism, which consists of a screw and piston with a double sealing function, an O-ring and a steel ball, which press against a spherical seat. The outside (D) and inside diameter (d) and the plane surface of the hub-side flange are machined for extremely smooth running. The piston and the cylinder are designed to cope with several thousand assembly/disassembly cycles.
Function: When the pressure screw is tightened, the double walled sleeve extends evenly along the shaft and hub and creates a secure connection. After the pressure screw is slackened, the ETP-Techno returns to its original dimensions can be easily removed.
