Metal bellows couplings with radial clamping hub

Description:
Material:
Hub in aluminium, natural finish. Bellows in stainless steel
Sample order:
nlm 23000-012,
D1 = 6
D2 = 6
(The hubs are supplied predrilled).
Note:
Short assembly times and an easy installation due to the radial clamping hub. Also, if the installation space is limited. The neccessary thightening torque of the clamping screw must be noted.
Assembly:
The seat shaft / hub is to be selected as transitional seat. Admissible seat clearance shaft / hub: min. 0.01 mm; max. 0.04 mm. E.g.
shaft: 28 k6
borehole: 28 F6.
Boreholes which are smaller than D min. are possible; but an optimal transfer of the nominal torque of the coupling can not be guaranteed in this case.
As the metal bellows consist of thin stainless steel sheeting, special care during fitting and disassembly is neccesarry. Damages to the bellows can render the coupling useless.
On request:
Desired hub holes D1 and D2 seperately with tolerance class or tolerance zone.
