2007 polaris outlaw 525 IRS rear bearing question

I recently had my mechanic replaced my torn inner CV boot. While removing the axle, the bearings pop out. I was instructed to replaced bearings. I ordered bearing and somehow it was different from I have. The bearing ordered were like sealed type. From what came out of the housing was knuckled ball bearing type. I tried searching for the right part by all searches leads me to the sealed bearing.
Can anyone help me in getting the right part needed.

Thanks...:confused:

I think you might be confusing a bearing with the CV joint at the end of the axle. is has a bunch of balls for the knuckle.
