Q: How are the parts assembled together for deep groove ball bearings?: Deep groove ball bearings are composed of inner ring, outer ring, steel ball, upper and lower cage.Assembly sequence: the outer ring shall be fitted with inner ring, the cage, the steel ball, the other cage, and finally the rivet (hole on the cage).

Q: What are the dimensional tolerances for deep groove ball bearings?: Deep groove ball bearings are radial bearings. In general, the upper and outer tolerance of bearings is 0, and the lower difference is a negative value. Such as deep groove ball bearings 6206, the bore diameter is 30mm, the deviation is 0~-0.01mm; the outer diameter of the bearing is 62mm, the deviation is 0~-0.013mm. The specific bearing tolerance is determined according to the standard size of the bearing and the basic dimensions.

Q: Deep groove ball bearings 61805, 16005, 61905, 6005, these 4 bearings bore 25, how many are four figures, and some five figures?: The standard code for bearings is 6 - 61805, for example, 6 for deep groove ball bearings, 18 for outer diameter and width size series, and 05 for internal size series. The code for the zero series can be omitted, so my bearing code is 4 bits and 5 bits. Specific bearing coding and naming rules

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: What are the differences between deep groove ball bearings 16004 and 6004??? 1 is that a separate row? What about 6004?: Are deep groove ball bearings, single row, no seal, their static load is different, there is a slight difference in weight.

Q: What are the characteristics of double row deep groove ball bearings?: Double row deep groove ball bearing with radial single row deep groove ball bearing 1.62 times higher than the carrying capacity, suitable for application in bearing configuration load capacity of a single row deep groove ball bearings of the double row deep groove ball bearing besides bearing radial load, also can withstand the axial load effect in two directions.

Q: Motor bearings deep groove ball bearings generally live for how long?: Bearing life and speed related, in general, the life of about 20 thousand hours

Q: Ordinary deep groove ball bearings replace cryogenic -60C grease. Can it work in an environment of minus 45 degrees? Does expansion and contraction affect the bearing greatly?: If the temperature range of lubricating grease is to minus 60 DEG C so the normal use of low temperature conversion rate is -45 degrees Celsius but depends on the actual conditions of your time and thermal design of equipment should have been taken into account only from fat considerations do not have to worry about

Q: What is what is the deep groove ball bearings, self-aligning ball bearings, spherical roller bearing is what: The 0 category is the deep groove ball bearing type.1 self-aligning ball bearing self-aligning roller bearing.3 class is the hope can help you

Q: See a lot of deep groove ball bearings, inner circle interference fit, the outer ring and hole clearance gap, the gap is roughly 0.04mm, what's the advantage of this cooperation? The hole is aluminum and the shaft is made of steel. If there is a gap, what is the meaning of the bearing accuracy?: Benighted people on earth, in most cases, axial interference fit, and the bearing seat is transition fit, what is the reason for it, please remember, no matter what conditions, the best results finally requirements of bearing during operation is not due to the relative movement axis and the inner ring, motion produces friction, the friction will have wear. Wear will produce radial movement, as the axis bearing seat is fixed, so the shaft with the interference; and then to the bearing seat, why should the transition fit, because the first convenient installation, second is because the bearing clearance, the first floor didn't speak clearly, the meaning is to first clearance in order to be able to rotate freely, and the problem of the stress buffer. As mentioned earlier, it is required that no matter what the working conditions are, the final operation will be required..... Why, that operation, bearing alone does not consider this problem can not be ignored, because the conditions, such as temperature, high temperature metal expansion, either axial or radial expansion, such as axial and radial expansion under high temperature, then you must be installed when the gap with the 1 floor is wrong, then the axial temperature caused by the length of variable length, this is a special case, which is the fixed side, without considering the fixed side view, side by side fixed bearings, shaft and bearing position has been fixed, the high temperature, the two bearing distance, this time must make with time gap side bearing let the lengthened shaft, can smoothly through the bearing, otherwise it is subjected to abnormal axial force, bearing damage quickly, remember the characteristics of deep groove ball, can bear large radial force of a radial force, so so Dry. Then we just assume is the axis, the bearing seat does not turn, if it is placed over the shaft, bearing seat, with the opposite, such as roller, to sum up, the 1 floor is misleading
