Table Saw Bearing - 'Splain Me These Model Number Differences

The front bearing on my TS Arbor is labeled as 6202RS. When I Google that number I get tons of hits for 6002-2RS. Many pages use both numbers for the same part. Is there a difference?
One example is this listing on eBay which lists the model number as 6202-2RS but uses 6202RS in the detailed description. Even the link uses both 6202-2rs and 6202rs.

The trailing code tells you what kind of shields or seals the basic 6202 bearing is equipped with.

These bearings are a commodity. It may be simpler to take the old bearing to a local bearing house. That way you´ll avoid mistakes, or getting junk bearings.

Hard to tell but the original part number may have been changed with a replacement part number or the numbers are different because of different manufacturers of the bearing. Typically products are designed around available bearings.

Yes.

IMO either of these would be an upgrade from the OEM:

Not an expert on bearings but all the specs appear to be the same except for one or two seals. Thinking with one you could pull the bearing out and pack grease every 50,000 miles or two to keep dirt out ???

Yout table saw uses a grease packed or oil lubricated arbour - so you pull one seal out of a 6002-2rs and you have a 6002-rs - install with the remaining seal facing out.

Do you know what kind of saw I have or are you just making an ass-umption?

IF the saw uses a 6202-rs bearinge it is a packed arbor.
If it's not a packed arbor you NEED the 6202-2rs Oil filled will not be listed as a lubrication point because it is filled with thick oil like gear oil - almost grease, but with no "soap".
A 2rs bearing is sealed and "permanently lubricated" -
I've worked with equipment with bearings for over 50 years
Sinse you have not seen fit to enlighten the group as to what kind of saw you have I can only go by what you HAVE said.
Have you taken it apart to KNOW it is not packed? Or to KNOW you have a 6202-RS bearing in there?
Untill you either tell us what saw you have, and/or what bearing IS in the saw, all we can do is the same as what you are doing -- ASS Ume

Perhaps you should tell Sears that.

Not on my saw.

Good to know.

Meh

Actually I did, but in another thread where it was agreed that the bearings were shot. However, in this thread, I specifically mentioned the type of bearing that is in my TS. Since I already know what bearing I need, I really don't think that the model of saw matters.

Yep

Old outside bearing

Old inside bearing, on arbor (tough to read, but it's a 6202RS)
https://i.imgur.com/JVGHin4.jpg
And just so no one can claim that the original bearings were replaced with the wrong ones, here's a brand new arbor, purchased from Sears Parts Direct, with the inside bearing that came installed on the shaft.
https://i.imgur.com/M2C51MX.jpg
And just to make sure we've covered all bases, here's the part at Sears Parts Direct, labeled with 6202RS:
https://www.searspartsdirect.com/product/ho3v4hg9f1-0009-113

Now that's almost humorous. Not only am I not assuming anything but I told everyone (well, apparently everyone but you) what bearing is in my TS in the very first sentence of my very first post of this thread.

I said IF you had not verified the bearing type by dissassembly - You have - so not an ASS Umption.
Does your 6202-rs have a seal on both sides? If it does, it is actually a 6202-2rs assembled with 2 seals for a 6202 rs. The bearings are the same. The seals are the same. The 2RS just has 2 seals instead of one. Would not be the first time the "wrong" seal was used in the assembly on a sears part (and not just sears either)
If it was a 6202-z it would be a "sheilded" bearing - a 2z or zz is double sheilded. It appears some suppliers are only stocking 2RZ or zz with instructions to remove one seal or sheild for rs or z applications.

Actually, what you said was "all we can do is the same as what you are doing".
You see the section that says, in no uncertain terms, "the same as you are doing"? If that's not an accusation that I was making an assumption, I don't know what is.
That doesn't even address the fact that I specifically told everyone (except for you, I guess) what bearing was in the saw in my OP.
Did you miss that or think that I was making that up or what?
Be honest.

Just some items I've found on the web...
Item 1: 6202RS Deep Groove Ball Bearings - SODIAL(R) 2Pcs 6202RS Closed with 2 rubber sealed to protect the bearing from dust or any possibl e contamination.
Item 2: 6202-2RS (6202RS) Sealed Mobility Scooter & Power Chair Bearings This set of two 6202-2RS sealed mobility scooter & power chair bearings is also known as the 6202RS.
Item 3: 6202RS Deep Groove Ball Bearings - TOOGOO(R) 2Pcs 6202RS 15mm Inner 35mm Ou ter Single Row Deep Groove Ball Bearing Closed with 2 rubber sealed to protect the bearing from dust or any possibl e contamination.
Item 4: uxcell® 2 Pcs 6202RS 15mmx35mmx11mm Sealed Deep Groove Radial Ball Bea rings Bearing has Rubber Seals to protect the bearing from dust or any possible c ontamination, also bearings are pre-lubricated with grease.
I could go on. It seems like the 6202RS is available with 2 seals from a variety of vendors. If Sears got it "wrong" it seems like a pretty common mistake.

It really doesn't matter what a parts site calls the bearing. It's what the bearing industry calls the bearing that counts.
By the old industry standard a RS bearing is sealed on only one side - a 2RS is double sealed A 2rs can be used in place of a rs, but not the other way around.
And you ARE aware there are 3 different 6002 bearings that are NOT interchangeable? 1/2 inch. 5/8 inch and 17mm bore?
Been stung on that one before. Just saying "be carefull" when ordering stuff on-line.
I have 2 6201-2rs bearings - both have 6201-RS on the seals and 6201-2rs on the box.

What really matters is if the bearing I receive is the correct bearing for my arbor. They can call it Susie as long as it matches the required specs.

Why do I care about the bore of a 6002 bearing?

Typo - it is the 6202 bearing that has 3 different bore sizes. The very bearing you are needing

The arbor of a table saw has a pair of bearings fitted into a housing, and the outer faces need to be shielded against sawdust; that means 'R' rubber seals. The inner, if you ever are expected to add oil, has to be 'S' or the oil won't get in.
So, -RS bearings might mean that some oil-regularly maintenance was required. Nowadays there's good evidence that RR with permanent lube could also work well (especially for a hobbyist who spins the saw up a few dozen hours a year).
