There are many kinds of tapered roller bearings, because of work requirements, test the external size is qualified, I want to make a test, to test the bearing is qualified, mainly inside and outside diameter and inside and outside the ring height tolerances, diameter ranging from 50mm--80mm, score less, look forward to your help, I thank you there are 322163311532215 main bearings, 313113002
Are you a bearing manufacturer or?The accuracy levels of the bearings are different, and the relevant tolerance levels are different. If it is not for your manufacturer, you can contact the supplier directly to check the data you want to check.If you are a manufacturer, you should have your internal size, accuracy, grade, and some, you can find the tolerance directly.
This is not easy yet. Do you think it's possible to make a standard check instrument yourself?!
There is one thing that measures the inner diameterPlug coneThe outside diameter of the tool has not been seenThe tool set up is the watch standYou check it outIs it too troublesome to check each one?
Less points, huh, huh?Bearings are tested with a dedicated bearing inspection instrumentTable seat:Outside diameter D913Internal diameter D923Height G904With standard and special micrometer (usually microkators and leverage comparator)Each inspection procedure has the corresponding inspection instructionYou can provide the job instructions free of charge to your bearings suppliers as a project to review their process controlAs for the instrument, you should pay for it even if your supplier offers itIf you buy the bearings in the retailers, then you have to pay for them yourselfThe work instructions may also have to be replaced by money
