Ikea NORDNES box with sliding doors - looking for spare part

Hello, I am desperate because my Nordnes box (item no. 16353) has a sliding door hinge (I hope this is the correct term :) broken - roller crumbled..... Spare part: I don't know where to get this from - there is an A stamped on it.

Does anyone know help?

THANK YOU VERY MUCH

best regards
chris

Hello, 16353 is only the manufacturer's number of the cabinet. Do you have a photo of the fitting?
