Sawzall Bearing Recommendation

[KDoug]

Hi, I'm still very new here, but I've been on Garage Journal daily for about a month now. So if this is the wrong place to post this let me know.

I was recently given a couple M18 Hackzalls that weren't working right, so I decided to see if I can fix them. It turns out, the only thing that is wrong is the bearings have gone bad. Milwaukee does not sell the individual bearings that go in the gearcase and on the motor shaft. I ended up having to put a new motor in because I couldn't get the bearing off the shaft. I was wondering if anybody could recommend a decent brand of bearings, I believe it is a 15x32x9.

Thanks

Here is the bearing.

I've had issues with bearings from Amazon. They sell a lot of Chinese **** that's barely good enough for a fidget spinner.

I've bought from these guys before, and would go this route myself:

Paranoid56, Thanks for the link, but at that price I would be concerned about the quality, that was the whole point in starting this thread. I want something reasonably priced, nothing high end though.

I've never had issues with bearings that I've bought from Fastenal...

https://www.fastenal.com/products/details/0474375?term=6002-2RS

$1.85 - Bearings Limited brand...

 

[metaldad]

motion industries (formerly berry bearing) has 6002 2rs in a timken, $22
and shuster (?) for $11.

Look in your area for an industrial bearing supply house. Take the bearings in and they can find replacements.

I have a alternator shop in my town that I've gone to in the past for bearings, I might try there too.
Thanks

Could you explain to the difference between the two Timken bearings, one is labeled C0 and the other C3.

 

[Wamsutta]

+1 on Motion Industries; that's where I get my bearings at.

 

[rlitman]

C3 has a looser fit. You want C3. C0 can bind up as it warms up from use, and is only for slow speed applications.

Ok thanks, is there anything else I should know before buying some bearings?

No ABEC rating means the bearing is probably ****.
Higher ABEC ratings make for smoother rolling, but higher than 3 is probably not worthwhile in your application (3 is the sweet spot for another reason I'll point out below)

On top of that, I see a lot of counterfeit ABEC ratings on Chinese bearings. The Chinese like to exaggerate (or make up) numbers to push their products, so if I see an ABEC 5 or 7 stamp on a no-name bearing, I can be fairly sure it's fake. My wife ordered some cheap fidget spinners from China, and on the first one I looked at, I noticed that both the central bearing and the three outer bearings all had ABEC 7 stamps. It spun nicely on the central bearing (it sounded rough, but spun because it was dry). But when I swapped out of the outer bearings into the center, it rolled about as well as a piece of hose spinning on a pencil. Now it comes as no surprise that they used this as a way to empty their reject bin, but even so, sending out the falsely marked parts leaves a bad taste in the mouth.

Because of that, I think it is less likely (though not impossible) that you'll see counterfeit ABEC 3 bearings. It would be like counterfeiting $1 bills.

Thanks, just looked through all that. Explained a little about C3.

 

[KDoug]

So I found these: https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/272064984996

Seems like a good deal. Now that I sort of know what I'm looking for I got to looking at the bearings I pulled out and noticed that they are Peer 6002RLAD. The ones on EBay are a little different model number, not sure of the difference.

Timken bearings are very good, I have used them with no issues at all. NAPA has bearings as well, they may even have Timken bearings in some sizes. For some reason 6002 sounds like the same bearings I have in my compressor motor. I replaced them with Timken bearings about 18 months after I bought the compressor back in the early 80's. They have given me no issues at all since then.

Timekin, skf Nachi, C3. Stay away from Chinese/no name manufacturers, as they over harden their bearing , leading to breakage. Bearing need to be hardened on the outer surface, softer on the inside.
SKF for example will harden outside of a race to a depth of a (EG.) 1/16 of an inch, the inner depth is softer so the bearing will provide wear resistance on the outside but inside softer metal keeps it from fracturing. This type hardening requires special manufacturing procedures/machines Chinese do not invest in, as they get away without it selling at cheap prices.
On Ebay try not to buy old stock bearing, as the grease could be over 10 years old, grease does have a life expectancy, especially older technology greases.

 

[pcmeiners]

That's a little advanced for manufacturers that don't even clean the grinding grit out.

Was only pointing out 1 example of poor bearing manufacturing procedures, I am sure there are plenty more.

thank you.

 

[KDoug]

Just throwing these choices out there to see what y'all think, I'd wondered about the grease in NOS bearings.

Nachi:

[pcmeiners]

get a Nachi, but I bet that one is 10 years on a shelf. The other has no inprint, could be from anywhere.

OMG it goes on a sawzall, it's not like this is a high-rpm application like a turbo in a car...

Buy one, slap it in, use the tool already...

They failed within two years of buying the sawzall new because Milwaukee put crappy bearings in them. It also didn't help that we were hard on them, but I want something that'll last just a little longer.

 

[pilotmotor]

i wouldn't be afraid of buying an old bearing you can pop the rubber seal out and regrease very easily.

For a bearing in a Sawzall is not the reason I try and pass on some knowledge. It might save a turbo rebuild some day.

 

[KDoug]

Are Koyo bearings decent? Here's a 5 pack for $25.

Excellent outlook!
