I was reading this thread: http://www.cafehusky.com/threads/wr-250-bearings.33643/#post-319142 Which apparently means that bearings have a standardized numbering system, does anyone have any links to places that actually explain how they assign those types of numbers? I have a busted bearing off of a piece of equipment, and have been unable to locate it anywhere on the internet.
There are lots of kinds of bearings. For a single row ball bearing they go by the bore of the inner part. There are series of duty, light to heavy with the balls being bigger and of course the thickness and outer diameter increasing as the duty rating goes up. There are inch series and metric series. But there are roller bearings, taper roller bearings, spherical roller bearings. needle bearings, and more I could think up and more I couldn't name. BDI is most likely nation wide though the place I used to go in person doesn't have a cash drawyer any more. http://www.bdi-usa.com/ Even Napa employees have the tools to get most bearings though I doubt most know how to use them. If you verify it is a single row ball bearing I could elaborate. If it is a taper roller beaing often the cone and the cup need ordered seperately. Some things are just kind of special orders by the factory of the piece of equipment perhaps incorporating a seal a special way or a special length. Fran
Not sure on all this numbering system but if you have the race and outer shell, take it in to a bearing store and match it up ... Outside and inside diameter sizes probably must be the same as original but sometimes the width can vary ... Good luck understanding all this .. http://www.timken.com/en-us/products/Documents/Bearing_Specification_Guide.pdf http://www.spb-usa.com/info-bearing-numbering.php
