Is this an official replacement part from Rancilio? and if it is, would this fit the Rocky?

Hi Ming
No these burrs are not purchased through Rancilio, too expensive. The burrs you require can be found here https://www.theespressoshop.co.uk/en/Rancilio-MD40-Rocky-Grinder-Burrs-LH-50x31x8mm---69000032/m-2889.aspx
