Re: Moss wheel bearing quality?
Most of these parts are generic, so they are just ordered from a bearing supplier. I suspect that the supplier varies according to their costs and availability. You can get the same thing by going to a bearing distributor, if you know the type no. There are Timken numbers in the Wiki, Spridgets-Tech Tips section, near the bottom of the page.
If you do use the Usual Suspects, shop around a bit. BP Northwest, for example, is much cheaper, and high cost does not equate to quality in this business.
