Description:
Material, surface finish:
Elastomer spider in polyurethane, shore hardness 98-A. Hub in aluminium. Conical ring in tempered steel
Sample order:
nlm 23021-010,
D1 = 6
D2 = 6
(The hubs are supplied predrilled).
Note:
This serie of couplings is particularly suitable for use in main spindle drives resp. boring spindle drives for high speeds. The two clamping ring hubs must be mounted on the shaft ends with the given thightening torque of the screw before the plug-in assembly. The assembly force can be minimised by slight oiling of the spider.
Assembly:
The seat shaft / hub is to be selected as transitional seat. Admissible seat clearance shaft / hub: max. 0.02 mm. E.g.
shaft: � 25 k6
borehole: � 25 G6.
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.
On request:
Desired hub holes D1 and D2 seperately with tolerance class or tolerance zone.
