Bontrager duster wheel bearing id

bladeone

Been searching the net for a while now to identify my cartridge bearings in the front, my bike is a remedy 7 2013. 26" same wheel as in the fuel ex, with a 15mm axle.
Reason I'm looking is my front bearing is slightly notchy and I'd like to get the bearings before I pull them out.

Can't seem to find the number of the bearing, checked trek bontrager.
Then order them from work or a bearing supplier.

Thanks Andy
