To withstand 5000KG radial force to use much deep groove ball bearing.
5T ah, 4 bearings, 5T, 2, 6308, and together, installation can meet the requirements. A single set of 6308 is not enough!
Recommend you choose 22310
You can use 6308-6310 of the bearings, this kind of bearings can still meet your requirements. If you choose the bigger one, it's not very economical. For reference only. Thank you
