I don't get credit for this. Wish I could remember from where it was liberated but have had it too long. Question here made me remember it so a general "thanks" should go out across the ether and the interweb to the original author. The 8885 is in the list.

NOTES, ETC:
On NSK bearings: “V” = rubber seal on one side; “V V” = rubber seal on both sides; “Z” = steel shield on one side; “ZZ” = steel
shield on both sides; “DU” = heavy contact seal one side; “DDU” = heavy contact seal both sides.
“Heavy Contact” = higher drag. Normally the “V V” seal is sufficient.
I have never seen “DW” on an NSK bearing.
Ball bearing mfgrs. all use their own numbering system, although many of them are similar to each other.
Fafnir: “P” = rubber seal, “KD” = steel shield, etc.
SKF: “RS” = rubber seal, “Z” = steel shield, etc.
No suffix = no seal or shield
Seals retain grease & exclude contaminants. Shields do not – they need an auxiliary seal to do that. Often ball bearings that
are sealed or shielded on both sides are cheaper (because they are more common). You can safely pry out the seal/shield on
the side where it’s not needed. I’ve listed mostly double sealed/shielded bearings in the chart. The “C3” designation on some ball
bearings a clearance designation (the clearance, or “fit”, between the balls & the outer race). “C3” bearings are common (probably
the most common), and can be used in many applications.
