16 series of ball bearing for pneumatic tools

Q:Deep groove ball bearings, 37 diameter, 20 diameter, what type of bearings?: Deep groove ball bearings, outer diameter 37, inner diameter 20 bearing type is 6904 (61904), 6904ZZ (61904ZZ), 6904-2RS (61904-2RS),Inside diameter: 20mmOutside diameter: 37mmThickness: 9mmDynamic load: 6370nStatic load 3650nLimit speed: 18000 r/minWeight: 0.04 kg

Q:What are deep groove ball bearings for?: Deep groove ball bearings can be used in gearboxes, instruments, meters, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, construction machinery, roller skates, yo yo balls, etc.;Deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row. The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing. Dust seal cover material for steel stamping, only to play a simple way to prevent dust into the bearing raceway. The oil proof type is a contact type oil seal, which can effectively prevent the grease from overflowing in the bearing.

Q:Can tapered roller bearings and deep groove ball bearings be installed in pairs?: Hello, tapered roller bearings and deep groove ball bearings are not paired installation, the reason is that they use in the design condition when it is not in accordance with a design to use, in addition they are 2 kinds of bearing different simply collocation together. Just like the cat will not enter the kennel forcibly entered the only fight back. I suggest you use angular contact if you need to accept the load and use it in pairs.

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:Handbook of mechanical design are provided for each type of deep groove ball bearing static load, I have a problem, if the load is greater than its own calculation of deep groove ball bearing static and dynamic load of a particular model but still use the bearing is as the product of the wheel would be directly damaged? I found in the calculation of the load is too large, the direct impact of the bearing life is shortened, calculated only a few hours, this shows that the model bearings in the work can only work these hours? But my boss told me that the load that I said just now is much less than the rated load. Can it be used more than rated?: Bearing rated dynamic load is greater than its rated static load, rated static load is generally rated dynamic load of 70%-80%, see bearing samples. Generally, the rated dynamic load of foreign bearings is 10% higher than that on the manual. Look at the bearing samples, it is best to see the sample rated dynamic load, do not look at the manual.

Q:There's a lot of trouble with the production process. We have a lot of rings and other accessories here. And the assembly. The so-called assembly, that is, the acquisition of rings and various accessories. Assemble the finished bearings and sell them.I think the process should be like this. Start with the ringRing: cutting plane and centerless grinding - zetoms hole chamfering -- dredging completed after heat treatment are then sent to the bearing factory.Bearing factory: automatic ring grinding (131201143 model) - ultra fine - cleaning ring - Union - pressure cage - cleaning product bearings - plus grease - gland - rust proof oil - Packaging - delivery: 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:Just learned in the selection of motor bearings, in addition to the deep groove ball bearing, the rolling bearing to meet the following conditions: 1. the C3 clearance speed is higher than the reference speed bearing 70%; so choose C3 clearance of deep groove ball bearings at what time the 2. temperature greater than 10 DEG C when the inner and outer rings? Younger brother every time with the coefficient of linear expansion and temperature rise to reduce the amount of clearance, and then refer to the bearings and shaft and bearing seat to determine the use of clearance, so that there are other deficiencies? Request for comment: In the selection of motor bearings, according to the user's use results, deep groove ball bearings are generally the upper half of the C3, that is, the clearance value of the lower half, more suitable for the motor in the light load, medium and high speed. The normal work windage involves many factors, and the calculation can only solve most of the problems. In many typical application conditions, there is a mature design, and comparing each other is a more reliable method.

Q:Deep groove ball bearings are how to assemble, I feel there is no way to assemble ah!: Now are the age of electrical automation, have automatic sets, riveting pressure, grease gland machine. Need to be detailed to find

Q:What's the difference between HRB's deep groove ball suffix 2Z and 2RZ?: 2Z for double sided iron cap seal! 2RZ is a non contact type sealing rubber!

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
