The least sketchy way to do this sealed bearing conversion

This damn Sachs snowflake has a needs a 12mm x 35mm bearing. Apparently those don't exist.

I can..

A: use ye olde 6201 12mm x 32mm and shim the 3mm. Green locktite. Bam. The bearing would still hit the lip on the inside of the hub + ya know spacer in the middle and all that.

B: use the 6202 15mm x 35mm and shim the axle.

Both methods are doable but both seem equally shitty.

2 of those and a 15mm distance bushing inside the hub (edited)

Nice, I can whip some of those up no problem

Re: The least sketchy way to do this sealed bearing conversion

Sweet, yeah if you can make your own then you can also make them long enough to function as your wheel spacers if you want, 2 for 1!

Re: The least sketchy way to do this sealed bearing conversion

I did the same thing but I cut the shoulder to go from 14 to 12 or whatever in the spacer itself, spacer stays put when you remove the axle. It's slick.

Been installed in that bike since like 2006 and still kickin'

Thinking about something like this. Gonna rough it out on the lathe and see how I like it

Damn! That is nice. I just used an old ZA clutch spring GUIDE? Not sure what they are called but the band that goes around the clutch segments where the spring sits. It has also worked for years. Access to a lathe is awesomeโ€ฆ.very jealous.

Just having a 7x14" mini lathe is so rewarding for moped shit. Just cutting wheel spacers, axles, making parts a little smaller etc is so bitchin'.

Re: The least sketchy way to do this sealed bearing conversion

did no one google?!

https://www.amazon.com/dp/B07T6TCXJV/

review is from a guy that installed these bearings in the wheel of his Honda C70. now i don't know anything about the brand, but is Amazon has them, your probably just not searching for it the "correct" way. I've seen old bearings specified with a fancy code instead of the dimensions (edited)

I did Google, but if the local company I go to who only sells belts and bearings tells me it doesn't exist, I tend to believe them regardless of what supposedly exists on amazon

I'm guessing that tendency has changed . ;)

Re: The least sketchy way to do this sealed bearing conversion

I've ordered bearings from Amazon that were listed as an "off" size like that but were not as advertised. There is a lot of misleading crap listed on that marketplace.

Re: The least sketchy way to do this sealed bearing conversion

Aww yes, the plot thickens. C70 axles are 10mm lol

Re: The least sketchy way to do this sealed bearing conversion

lololol dangit!

I'm pretty sure Italian 5 stars need this same funky bearing, at least mine did

They are 17" 5 stars with z sprockets tho, so maybe Sachs?

Anyways: I found them at an overstock sale coming from Brazil. They were made it Japan in the 70s

Which reminds me that I need a sprocket for one of these suckas.

Hmmm, I'm not sure about your wheel but I'll snap a pic of the bearings when I get home

FYI loctite green bearing retaining compound comes in like 2 variants

One takes up to like .015 of slop and one goes to 0.25

Nay, they cannot be trusted. the link i provided to amazon also had a "bearing ID" that did not match the correct specs. *shakes fist at Amazon*

Remember that upgrading to a 12mm axle was also the goal in this instance

Huh, well these are 36x12 I guess

But these are what I used, and they are NLA as well

Maybe you should measure those bearings .

6201 are 32 mm outside . ;)

Re: The least sketchy way to do this sealed bearing conversion

๐Ÿ‡ฎ๐Ÿ‡น๐Ÿ’ฆ Of the Loin /

They are 361201 though

Slight difference in numbers ;)

Hmm , why would the seal have 6201 ? Maybe uses the same seal as ... just the inside bore is different .

True the 361201 measures :

35 mm Outside diameter

12 mm Bore diameter

10 mm Width

Ok so the 361201 from SKF is a viable replacement. Hmm maybe my boys at the shop we're trying to keep the 11mm width in there as a factor. Totally irrelevant for wheel bearing swaps though.

If you find a good source id buy a couple spares
