ETP-TECHNO is specially designed for applications where fast frequent changes or adjustments, with highprecision are needed.ETP-TECHNO can be mounted/dismantled 1000´s of times.It is very easy to mount, only one screw, ETP-TECHNO in a tight space, and it also has extremely good concentricity.ETP-TECHNO is thehigh precision joint among the ETP hub-shaft connections.

CONSTRUCTION

•Possible to mount in tight spaces.The pressure screw is tightened in the radial direction to the shaft.•Small built-in dimensions.•The hub can be adjusted easily and accurately.ETP-TECHNO is also suitable as a base for customer adaptedsolutions.See the section for ETP-Special designs. ETP-TECHNO consists of a double-walled hardened steelsleeve filled with a pressure medium, and a flange.The flange part contains the pressurizing mechanism which consists of a screw and piston with double sealing function, an o-ring and a metallic seal with a steel ball which is pressed against a spher-ical seating.The outer, D, and inner, d, diameter and the side of the flange towards the hub are accurately machined for extremely good concentricity. The piston and the professional cylinder are designed for 1000´s of moun- tings.

OPERATION

When the pressure screw is tightened the double-walled sleeve expands uniformly against the shaft and the hub thus creating a rigid joint.Dismantling of the joint is done by loosening the screw.ETP-TECHNO returns to its original measurements andcan easily be dismantled.

QUALITIES

The unique hydraulic principle gives a great number of advan-tages: •Fast mounting/dismantling.Only one screw needs to betightened.•Extremely good concentricity, also after several mountings. •Can be mounted/dismantled 1000´s of times. When the pressure screw is tightened to the recommendedtightening torque, Tt, the steel ball professional seals against the sphericalseating.ETP-TECHNO will have created a uniform surfacepressure against the shaft and hub. 12
