YST bearing seals
 

I have the YST bearings and the seals wear out, anyone know where I can get replacement seals? http://i65.tinypic.com/65u8et.jpg

is that BB, or what bearings?

Those are some old style cups. Are these from a fat bike?

Yes BB bearings on my fat tire bike, Mongoose.

Looks like the one-piece crank bearings. If you don't find any bearings, probably need to get a new crank and proper bearings. either square taper and sealed cartridge, or better external bearing type. but that may cost more than the Walmart bike cost to begin with.

The YST bearing set isn't expensive, I've bought two just because the seals broke. Don't want to keep buying the set if I can find new seals. Maybe some place like Grainger's.

As you learned, this is all Walmart quality. No real bicycle uses those type of bearings, so there is no market for high quality types. No offense to you and your bike, but there is a reason why none of the better bikes uses that type.

That was helpful, thanks.
