ExpaHub

Economical connection of hubs and shafts, without the need for parallel keys

The SCHAAF ExpaHub can be used anywhere where a flange or a hub with a cylindrical ID has to be mounted on a shaft. Both conical sleeves between the flange or hub and the shaft are pressed together using a hydraulic tool, thereby generating the required radial compressive forces.

Ventajas

Lowering of costs, since the flange has not to be forged on shafts or axles, respectively lowering of material and chipping costs
High torque transmission, completely free from backlash
Separate, removable Hydraulic Nut – only one for a number of couplings
Torsionally and flexurally rigid connection even with sudden changes in the rotational speed, torque, or direction of rotation
ExpaHub can be removed simply and quickly even after years of use
Reusability after removal – helps reduce costs
