Will these fit the Arrma Mini Kraton hubs?

Yes. The 7x14x4mm size is the hub bearing size for the Mini Kraton, and the ARA-2713 is the listed replacement part.

Are these sealed or shielded?

They are shielded, with double protective shields on each bearing. That keeps dirt out but means you cannot pop them open to relube.

Four bearings. That covers both sides of one axle pair, so check how many positions you are servicing before ordering.

They are the same spec as the kit parts. They restore smooth operation but do not add life over the originals.

No. Press them into the hub by hand or with a bearing driver, seating them square so the shields are not damaged.
