Do you mean deep-groove-ball bearing or roller. There is a huuuuge difference in IMSB terms. Don't get us started on that again!
Filtration - suggest you research the difference between the OEM filter and the LN full flow+Napa Gold spin-on filter. By-pass is a more significant risk than filter pore size according to the experts.

I am referring to both roller and ball. By filtration I am referring to the the filter efficiency, not bypass, ( I have LN, NAPA Gold and Filtermag to eliminate bypass) this is not the same thing. The Filtration efficiency of most filters is only to ~10 micron first pass. This means there is always some particles that simply pass through the filter.These are continuously circulating to some degree. These particles are fine in a plain bearing where there is no contact and the bearing rides on a film of oil that is greater than this particle size. That is not true with a roller or ball bearing where the balls have contact with the races, and therefore do not like debris.
