Q:I want the standard is best GB, and if other mechanical standards are also ok. 2, mainly to bearing diameter tolerance (preferably all grades have).

Deep groove ball bearings are the most commonly used rolling bearings. The utility model has the advantages of simple structure and convenient use. The utility model is mainly used to bear radial load, but when the radial clearance of the bearing is increased, the ball bearing has the performance of a certain angular contact ball bearing, and can bear the combined load of radial and axial. When the speed is higher and the thrust ball bearing is not suitable, it can also be used to bear the pure axial load. Compared with other bearings of the same size, the friction coefficient of this kind of bearing is small and the limit speed is high. But it is not shock resistant and is not suitable for heavy load. The deep groove ball bearings are mounted on the shaft, and in the axial clearance of the bearing, the axial displacement of the axle or the two directions of the outer shell can be limited, so that the utility model can be positioned in an axial direction in both directions. In addition, this kind of bearing also has a certain ability to adjust the heart, when relative to the shell hole tilted 2 'to 10', still can work normally, but it has some influence on the bearing life. The deep groove ball bearing holder is mostly steel plate stamping wave cage, and the large bearing adopts the metal solid cage. Size tolerances and rotation precision tolerances of deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, pumps, agricultural machinery, textile machinery and other deep groove ball bearing according to GB GB/T307.1-94 divided into P0, P6, P5, P4, P2 five precision grade. They are equivalent to the international standard ISO492, German standard DIN620, Japanese industrial standard JISB1514, and the corresponding accuracy grade of the United States national standard ANSI/AFBMA STD20.

Q:To withstand 5000KG radial force to use much deep groove ball bearing.

5T ah, 4 bearings, 5T, 2, 6308, and together, installation can meet the requirements. A single set of 6308 is not enough!

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:Use of deep groove ball bearings?

Today, explain the structural features and application fields of deep groove ball bearings.Inside and outside raceway of deep groove ball bearing is arc shaped deep groove, the radius of channel is slightly larger than the radius of ball. Mainly used to bear radial load, but also to withstand certain axial load. When the radial clearance of the bearing increases, it has the function of angular contact ball bearing, which can bear greater axial load, and is suitable for high speed rotation. The bearing can still work normally when the shell hole and the shaft are inclined 8 'to 16', but the service life of the bearing is affected. When the speed is higher and the thrust ball bearings should not be used, the bearings can be subjected to pure axial load.Deep groove ball bearing the general use of a synthesis consists of two parts stamping steel cage, but the large size or high speed bearing with solid cage, the cage with the pressing cage by ball cage guide, usually by the inner or outer wall to guide the high speed deep groove ball bearing.Compared with other bearings of the same size, deep groove ball bearings have the advantages of small friction coefficient, low vibration and noise, high limit speed and high accuracy. It is the preferred type of bearing in the selection of users. However, this kind of bearing is not shock resistant and can not bear heavy load.Deep groove ball bearings are simple in structure and easy to use. They are the largest in production and the most widely used. Widely used in automobiles, household appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total output of bearings, and it is the most widely used and the most popular and the cheapest type of bearing in our country.

Q:Deep groove ball bearings how to make, how to put in the steel ball?

Deep groove ball bearings are mainly divided into inner and outer rings, steel ball, cage, sealing ring (dust cover). The utility model is processed into the inner ring and the outer ring by the bearing steel cutting, and through the material cutting, trenching, heat treatment, internal and external grinding, flat magic, grinding, placing the ball bearing with the cage, separating, oiling, packaging, and so on.Simply put the outer ring well and then put the inner ring. Here, the inner ring is placed inside the outer ring and then placed into the ball. Make sure that the ball is secured to the cage.

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?

What I want to say is that no matter which country or the manufacturer, no matter how good the bearing is, there is always a rated load, but it is only a good load on the bearing. If it exceeds the rated load of the bearing, I suggest that you choose another larger rated load, or reduce the force on the bearing. More than the rated load is still used, as you said, the biggest impact is life, the more critical it is, the less it can be designed.

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:What is the function of the bearing dimension series?

The bearing size series is mainly designed, manufactured and assembled to help the builder find the corresponding bearings quickly according to size, thus greatly reducing the time and improving efficiency.There are five following series:A. deep groove ball bearings 600062006300, 6400;B. deep groove ball bearings with 6400-N grooves, 6000-N, 6200-N, 6300-N, and so on;C. a deep groove ball bearing with dust cover, 6000-Z, 6200-Z, 6300-Z, 6400-Z, 6000-2Z, 6200-2Z, 6300-2Z, 6400-2Z with both sides of dust-proof cover;D. a deep groove ball bearing with dustproof rings (contact), 6000-RS, 6200-RS, 6300-RS, 6400-RS, 6000-2RS, 6200-2RS, 6300-2RS, 6400-2RS;E. one side with a sealing ring (non-contact) deep groove ball bearings, 6000-RZ, 6200-RZ, 6300-RZ, 6400-RZ, two side non-contact deep groove ball bearings, 6000-2RS, 6200-2RS, 6300-2RS, 6400-2RZ type

Q:Are deep groove ball bearings rolling bearings?

Rolling bearingsRolling bearings means the inner ring is fixed, the outer ring is rotated, or the outer ring is fixed, and the inner ring is rotatedThe sliding bearings are bearings, left and right, or slide forward and backward. He does not have a rolling body, such as balls, rollers, and needle rollers

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!
