Q:Rated speed of deep groove ball bearings
LZ, look at the SKF manual!SKF's deep groove ball bearing manual is so marked. You can look at other brand manuals.For example: Japan's four major companies NSK, NTN, KOYO, NACHIGermany FAGAmerican TIMKENThese brands of ordinary deep groove ball bearings, performance parameters are very close, can be compared more. SKF really do not understand, but the quality of bearings are indeed commendable.
Q:Do deep groove ball bearings come with a top wire?
What's the effect of your top wire? As far as I can understand, only the bearing unit with top wire is used to fix the outer ring of the bearing on the bearing seat
Q:Selection of tolerance fit for deep groove ball bearings
Bearings are generally bearings and holes transition or gap, the use of special use of interference, if the choice of interference, the bearing holes selected N7, P7, axis selected N6, P6, hole tolerance increased level. Upstairs K7 is a transition fit, but also can choose, in general, if the requirements are not high accuracy, you can use the bearings and holes transition coordination.
Q:Why deep groove ball bearings have clearance fit?
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
Q:What are deep groove ball bearings for?
Bearings are, first of all, an industrial product and also a consumable. Its function is to reduce the friction coefficient between two opposite moving objects, or to reduce the friction coefficient of the advancing object, and to support the object, also called support.
Q:The deep groove ball bearing rubber ring is too thick. What's wrong with it?
It has the advantages of large compression deformation, large sealing pressure, large friction force, short service life and poor damping effect. It is best to design to the size required. Personal advice for reference only!!
Q:Why deep groove ball bearing dynamic load static load
You look at the rated dynamic load and rated static load calculation methods and principles, it is estimated that you can easily solve the problem. If you don't understand, I suggest you look at the design of rolling bearing Changsen million "". Jia Qunyi's "rolling bearing design and application" of these two domestic bearings design classic monographs.
Q:What's the difference between the rubber cap and the iron cover of the deep groove ball bearings?
Iron cover only dustproof, waterproof rubber cover, dustproof and waterproof
Q:What does "deep groove ball bearing" mean 16005 or 16 mean?
As mentioned above, 16 is a thin walled bearing. As in the 68 series of 69 series, it belongs to the thin wall bearing.
Q:Deep groove ball bearing and angular contact bearing are used at the same time
Bearings shall be installed in at least two conditions, erection and horizontal (horizontal) installation
