Bearing question?

[bounce03x]

I need to buy new bearings for my Sun trike. The bearings are a 6202z. Im searching around and they offer ex. 6202, 6202z, 6202zz etc

What are the exact differences?

Eventually Ill be putting on an engine kit.. so what would be my better route?

Also whats the cheapest place to get them?

Thanks

Z = shielded 1 side

ZZ = shielded 2 sides

The ones on my bike state z but are double sided. So either would work?

There is no point in buying single shielded bearings. Ebay is a good for bearings in small quantities and reasonable prices.

by loose packing your bearings you will be able to fit 1 to 2 more balls in there than if they were in cages. And it's more economical too!
