Shaft Coupling 30 mm 12.5 NM - drill holes selectable | e.g. for CNC, stepper motors, etc

Item number: XB30

EAN: 4251346438231

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.

For the connection of two shafts we offer you shaft couplings with different drill holes. The shafts are connected on both sides, the strength can be adjusted with a headless screw.  

These shaft couplings are 40 mm long and have a diameter of 30 mm and can absorb a constant turning moment of 12.5 up to NM and a maximal turning moment of up to 25 NM. No matter the same or different drill holes - you can choose the correct drill hole for you demand!
