Product Description:

Specification:

Deep groove ball beaings composed of four basic parts: Inner ring, outer ring, ball and cage. In normal operation cases, inner raceway, outer raceway and ball mainly bear load, and the cage separate and maintain a stable effect for ball. 

       

Product Features:

Deep groove ball bearing belong non-separable bearings and structure is simple, easy to use,  Mainly used to support radial load, also can bear a certain amount of thrust load. Increase the bearing radial clearance, has the heart to the nature of the thrust bearing, can bear the larger axial load. This kind of bearing can limit the two directions of the axial movement. According to the size of the clearance allows inner and outer relative tilt 8 '~ 16'. 


Product Application: 

Deep groove ball bearings the most widely used in mechanical industry.     Such as precision instruments, low noise electric motor, automobile, motorcycle, woodworking machinery, textile machinery transmission shaft, mining machinery, electromechanical equipment, plastic machinery, office equipment, medical equipment, fitness, national defense, aviation, aerospace and sports equipment and general machinery, etc.

Tolerance:

Standard deep groove ball bearings with average level, all consistent with GB307.1.


Radial clearance:

Standard deep groove ball bearings with C2, standard(CN), C3, C4 and C5 level internal clearance, and all consistent with GB4604. We also can produce the internal clearance as the customers requirement.

Q:Do deep groove ball bearings come with a top wire?
Deep groove ball, yes, but it's non-standard. What's your model?
Q:What's the difference between 6000-6012 and 6200-6212 in deep groove ball bearings?
Thickness difference. External diameter differenceTake 6000 and 6200 for example6000:10*26*8The 6200:10*30*9 6000 will be thinner relative to the 6200 wall!The bearing capacity will be smaller!
Q:The difference between deep groove ball bearings and thrust ball bearings
Thrust ball bearingBasic rated dynamic load ratio: 1; limit speed ratio: low; axial load capacity: can only withstand a one-way axial load (two-way thrust ball bearings can withstand two-way axial load); axial spacing: II (two-way thrust ball bearings for I); performance and features: can only bear the axial load, centrifugal force at high speed big ball and cage wear, severe fever, loss of life, so the speed limit is very low, in order to prevent slippage between the steel ball and the raceway, work must be added with a certain amount of axial load, and the axis must coincide with the axis to ensure the uniform distribution of load of the steel ball.Deep groove ball bearingBasic rated dynamic load ratio: 1; limit: high speed ratio; axial load capacity: a small amount of axial spacing; I; performance and features: mainly bear radial load, also can withstand axial load small, equivalent friction coefficient at high speed, can be used to withstand pure axial load, work allow the inner and the outer axis deviation is less than or equal to 8 points to 16 points, the lowest price of mass production.
Q:What does "deep groove ball bearing suffix" "MA" mean?
Deep groove ball bearing suffix "MA" means: machine, brass holder, outer ring boot.
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:What's the difference between the rubber cap and the iron cover of the deep groove ball bearings?
Outside the gear case, block the outer ring of the bearing or block the end cover of the bearing bore. It is called the bearing cap. The rubber cap and the iron cover of the bearings are more common,The role of bearing end cover is an axial fixed bearing, two is a sealed protection role, to prevent the bearings into the dust, etc., into the bearing, causing damage.The bearing end cover is fixed on the bearing seat or the bearing chamber, and if the shaft is fixed on the shaft, the sealing diameter is increased, and the sealing is difficult.Use bearing rubber cover for dust and sealing can be waterproof, but the friction speed is larger, and the iron cover is low, so the heat dissipation performance than iron cover; the plastic cover is divided into contact and no contact, but it is similar, there are differences of seal and friction on.The use of iron cover more, the main role is dust. Iron cover speed is higher, but because it is iron, so it is not waterproof
Q:How can we split the deep groove ball bearings?
The steel cage can be disassembled first.
Q:Compared with plain bearings, what are the advantages and disadvantages of deep groove ball bearings?
2, radial clearance is relatively small, radial angular contact bearings can be pre tightened, can be used to eliminate pre clearance clearance, high precision operation;3, under normal conditions, the efficiency of rolling bearings and liquid power lubrication bearings, but the mixed lubrication bearings higher;4, for the same size of the shaft diameter, the rolling bearing is wider than the sliding bearing, so that the axial structure of the machine is compact;5, a high degree of standardization, mass production, consumption of lubricants less, easy to seal, easy to maintain, do not need to use non-ferrous metals, low cost.Two, compared with the sliding bearing, deep groove ball bearings shortcomings:1, vibration and noise;2. Radial dimensions larger than plain bearings;3 、 poor ability to withstand impact loading;4 、 under high speed and heavy load, the bearing life is low.
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: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
