There are internal and external 22220CA bearing diameter of the actual tolerance?
21322CA outside diameter 240, inner diameter 10022220CA outside diameter 180, inner diameter 100A little does not understand, you ask, their two bearings all are to match the lock to apply tightly, can not say any inside and outside diameter toleranceBesides, the outer diameter tolerance of the bearings is 0. I hope I can help you
Do not process your bearing hole from +0.2 to +0.5 (mm). If so, your bearing socket is waste.You see a book with the book, have bearing on what kind of load to adopt what fit to write clearly.
The internal and external tolerances of the bearings are lower deviations, that is to say, the maximum limit is 0In theory, you 200 ~ 500um is casually put in, as long as not right, especially forbidHave a problem but also to the outside diameter of the bearing processing, there may be a fake, fake market now can do more.The outer diameter of 240 and 180, you can use a card or caliper, although not very accurate, but you and +200 to 500um ratio is no problem
