Shares parts with KTM/Husqvarna but very expensive and not load bearing so not worth replacing IMO. To completely overhaul the engines bearings you'll need a total of 13 bearings for the crank cases.
I have spent all day on this and I THINK it's correct. I've checked and cross referenced the part numbers and my existing cases and have tried to marry up the numbers to real-world buys. If there is a mistake please let me know and I'll update the table.
