I’ve been using qualitybearingsonline (no affiliation, just a happy customer) as my bearing source and getting SKF non contact seals (-2rz). I picked SKF due to past good professional experiences with them. At some point in an unrelated conversation with one of their applications engineers I asked about the original shields vs seals vs non contact seals and was basically told that it shouldn’t matter at that RPM, so I might as well be a bit better sealed at less than $1 difference.
