Q:Which type of deep groove ball bearing has an inner diameter of 10MM, an outer diameter of 20MM, and a width of 15MM?
Internal diameter 8MM, outer diameter 22MM, width 14MM, double row ball bearing, Wuxi one male bearing
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:Rated speed of deep groove ball bearings
The maximum speed of various bearings can be checked by table, and the ultimate speed of deep groove ball bearings is very high. But, "why is the rated speed of deep groove ball bearings (reference speed) greater than the limit speed, greater than almost double?". Only deep groove ball bearings are like this?" Where does that come from? No, it will damage the bearings very soon.
Q:Angular contact ball bearings or deep groove ball bearings for vertical motors. What is the minimum motor noise?
If installed properly, the deep groove ball will be less noisy! Angular contact bearings have much better bearing capacity!
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?
Online summary of the next answer to you.At low temperatures, the viscosity of the lubricant is even frozen, and the system work load increases, resulting in poor lubrication and accelerated bearing damageObjects have the nature of expansion and contraction, bearing, bearing and the like.Material shrinkage is different, so that the structure deformation, stuck.One end of the shaft is mounted with a pair of cylindrical bearings positioned as a shaft,The axial movement of the axle is restrained, and the other end of the shaft is supported by rolling bearings only to the radial force,In the axial direction, it varies with temperature and moves axially in a certain range. Such a structure is better.Low temperature greasePhysical condition: semi fluid color: Brown odor: fat oilSolubility: soluble in most organic solvents, water soluble: insolubleUniway LIX 22 PA grease is a kind of grease based on poly alpha olefin oil and compounded with lithium soap as thickener.The grease has a wide temperature range, high drop point, high performance oxidation inhibitor, low base oil viscosity and low temperature resistance.
Q:Deep groove ball bearings are how to assemble, I feel there is no way to assemble ah!
Press in. All right, deep trenches and shallow trenches.
Q:Deep groove ball bearing production process
The first step is forging forming, annealing, and machining, heat treatment and, to 58-62 degree, then the rough grinding, fine grinding or tempering stability, ultra precision grinding, reach the oil standard, then the rolling body and the inner and outer ring, a retainer, antirust oil - Packaging - hair the goods. Indicate that GCR15 or GCR15SIMN material is selected according to the thickness of the bearing
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: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 the benefits of SKF deep groove ball bearings?
SKF is the world's veteran bearing producer, accounting for the world's highest number of bearings! Its material has a certain pre potential! As for the benefits, compare with NSK, just like apple and Samsung, depending on the user's choice
