68 series ball bearings for Pneumatic tool bearings，motors

Q:What's the difference between 6000-6012 and 6200-6212 in deep groove ball bearings?: 6 means deep groove ball bearingsThe second bit indicates the width of the series. The model you call here is a narrow series, omitting 0The third digit represents the diameter series code, 0 of which is the special light and the 2 is lightPosition four or five is the inner diameter code, and your number is 12, or 60mm

Q:How can we split the deep groove ball bearings?: 1, if there is no open bearing seal ring or a dust cover retainer is a metal or plastic material, as long as the screwdriver sharp objects such as the retainer off well. But once the metal retainer is removed, the stamping tool is needed.2, with sealing ring or dust cover of deep groove ball bearings, this kind of bearings as long as remove the outside dust cover or sealing ring, let me according to the above way to remove it. Similarly, if there is a metal dust cover, then there must be a stamping tool to remove the new dust cover.

Q:How are deep groove ball bearings made?: Suggest you go to the website of professional spot to have a look

Q:I use a deep groove ball bearing now, model is GB/T 276-1994, a large diameter 90, 50 paths, 20 thickness, requirements of bearing outer ring arranged on a bearing seat fit, the inner ring is mounted on a rotating shaft, and the fit, I don't know how to choose the tolerance than the more appropriate. The outer ring with which to choose tolerance, inner and choose? Please expert pointing: In fact, the bearings are not strictly matched, if required, a little interference fit, 0.1 surplus can be

Q:If you do not have this specification, there are similar, please say, and, incidentally, with the approximate specifications, thank you!: Is there a problem with the sibling's parameters? This size should not be so wide inside and outside the bar

Q:To withstand 5000KG radial force to use much deep groove ball bearing.: Recommend you choose 22310

Q:Motor bearings deep groove ball bearings generally live for how long?: This is mainly based on the processing accuracy of your motor, equipment load, bearing installation and so onIf all of the above to do regularly, the use of rubber sealed maintenance free bearings, the general use of two years (eight hours per day) or so, there is no need to replace bearings.But if the condition is used, the bearings should be maintained after one year (cleaning old butter and adding new high temperature resistant butter)!

Q:At present only rough calculation is used to choose what kind of bearings. Load 5 ton car, four wheels, need four bearings. What kind of bearings need radial load?.: Each wheel bearing 1.25 tons, you see the bearing radial load of 1.25 tons on it

Q:Deep groove ball bearings have an inner diameter of 25 and an outer diameter of 47. How much is the tolerance of the shafts and jackets that match it?: What do you think you should do with it?.See what brand you use, the general use of NSK bearings.There are two kinds of thickness commonly used, one is 8, and the other is 12I think your bearing is generally used in interference fit (FIT) axis should be 25 deviation is under +0.021 bias is 0 on the 25 bearing diameter deviation is +0.048 error is +0.035 H7/s6 but normal bearing diameter using heat up method to cooperate. I hope you can absorb. Outside diameter 47, the upper deviation is +0.033, when the deviation is +0.017, the hole with the outer diameter 47 is the upper deviation is 0.025 H7/n6I hope you understand. I can't make myself clear on thisI'm using the base hole system. I don't understand this one. I am a mechanical engineer

Q:What's the model for deep groove ball bearings with an inner diameter of 20 and an outer diameter of 50?: Standard product, without this size.1., according to your size, that is non-standard, or a manufacturer for customers custom-made size (belongs to non-standard)2. size error, the outer diameter may be 52, and if it is 52mm, then the model is 6304 (the old code 304)
