Self-centering shaft-hub rigid coupling
WMH Herion
medium-high torque
limited installation time
restricted hub diameter
very low surface pressure
Tolerances, surface fnish:
maximum allowable surface fnish:
Rt max 16µm (Ra 3 µm - Rz 13 µm)
shaft tolerance = h 8; hub tolerance = H 8
Axial movement:
During screws tightening the hub has no axial
movement with respect to the shaft.
