Item number: XB20

EAN: 4251346438217

With our shaft couplings you will receive the optimal possibility to convey turning moments. CNC-Milling, portal milling machines, conversions from conventional machines to CNC-technology are only a few application possibilities for shaft couplings.

The coupling consists of two out of aluminium manufactured clutch docs with different drill hole diameters, a coupling star out of plastic for the transmission of the turning moment and compensation of angle errors between the shafts.
