Description:
Material, surface finish:
Hub in aluminium, natural finish. Bellows in stainless steel.
Sample order:
nlm 23002-0004,
D1 = 3
D2 = 3
(The hubs are supplied predrilled).
Note:
The clamping of the hub by means of a grub screw is a cost-effective alternative for the Metal Bellows Couplings with radial clamping hub (23000). Short assembly times and an easy installation due to the clamping hub with grub screws. Also, if the installation space is limited. The neccessary thightening torque of the grub screw must be noted. For easy disassembling we recommend to fit out the shafts with a face surface.
Temperature range:
-20 °C up to +150 °C.
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: � 5 k6
borehole: � 5 G7.
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.
