R + W presents metal bellows couplings up to 100.000 Nm. The torsion-resistant fasteners have been completely redeveloped due to market demands in the last two years. Compared to the currently available multi-disc clutches, these products feature a continuous homogeneous welded joint (hub bellows) instead of the punctiform screw connection (hub disc packs).
The BS1 flange joint, BS4 keyway and BS6 conical hub hubs are five series with torque ratings between 10.000 and 100.000 Nm. Bore diameters from 50 to 280 mm can be covered and the maximum operating temperature is up to 300 ° C. Thus, the use comes, for example, directly in the steelworks in question. The optional version in Atex version offers further applications in open-pit and underground mining. The symmetrical design allows high speeds up to 1500 min-1 be driven. Depending on the size, the double cardan joint compensates for a lateral offset of up to 7 mm.
