I run an ISO 220 oil on my front bushing/bearings. It is a total-loss system in that it drains into the chip tray and out a few casting holes onto the floor
I think iso32 was too thin, iso68 is ok for the ways (I use a way oil that's sae30 for that)
The debate will rage on as there are a million opinions . If you google plain bearing oil grade you'll see what I mean
Here is a link to a Mobil brand. https://www.mobil.com/en/industrial/lubricants/products/morgoil-220-oil
My lathe came with grease zerks on those bearings (yikes) but I switched them out and put oilers on. Took it all apart and cleaned it out.
I also check my bearing temp while running and use that as a guide for bearing cap tightness and oil throughput
