Donepart 6001 Bearing 6001-2RS C3 High Speed 12mm x28mm x8mm Deep Groove Bearings Double Sealed for Motors, Bicycle, Wheels, Power Tools, etc. (4pcs)

My bearings needed to be replaced in my go-ped and these fit the 1st time. And still running.

These bearings appear to be high quality, although they did not fit or work for me. They are exactly the size listed by the seller. My required bearing were very close to this size and I assumed, that these were the one. My fault. Measured again on product arrival and they are exactly as advertised. Fortunately, the seller sells the bearing I need and I have ordered the correct bearing. I will just keep the bearing I ordered, so I have no info on return process.

Ordered to replace mountain bike wheel bearings, so far rolling smooth, still need to see if they hold up long term. Only one side had grease, remove both seals and grease properly before installing.

fit like a dream

Had to replace the wheel bearing of an evolur stroller. Works great!

Did what they were designed to do

I used these to repair a set of feathers that the bearings had fallen apart. Good fit and so far holding up well.

They are will built. I use them for 49cc engine gear boxs.
