Help with headset bearings

I have a headset that is grumbling, lower bearing only at the moment, but I thought I'd replace the top and bottom bearings at the same time. The headset is an Acros AZX-212 AH, 1-1/8", tapered, HSZS 44/286-ZS56/40 W

I understand the "1-1/8", tapered" part of the description, but what does the rest of it mean?

What size bearings do I need to order that fit with that? Are they plain roller bearings, or is either of them an angular contact bearing? What width are they?

I tried the "cane creek headset finder" but the bike isn't in it.

Any help would be appreciated. :)
