To be certain you want to read the bearing number from the bearings in your hub. This is simple to do, remove the pre-load adjusters from the axle and then you should be able to read the number.
Google that number and you will find websites selling them, or take it to your local bearing/fastener shop.
SKF, FAG, and NSK are all recommended bearing manufacturers. I would avoid buy from eBay and Amazon due to fakes.
