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'.

deep groove ball bearing 3

Q: What are the benefits of SKF deep groove ball bearings?: 1, under normal conditions, SKF deep groove ball bearings and hydraulic power efficiency of the same bearings, but more mixed lubrication bearings higher;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, for the same size of the shaft diameter, SKF deep groove ball bearings wider than the sliding bearing, can make the axial structure of the machine compact;4, most bearings can be subjected to radial and axial loads simultaneously, so the bearing assembly structure is simple;5 、 consumption of lubricant less, easy to seal, easy maintenance;6, no useful non-ferrous metal;7, a high degree of standardization, batch production, low cost;

Q: At present only rough calculation is used to choose what kind of bearings. Load 5 ton car, four wheels, need four bearings. What kind of bearings need radial load?.: Each wheel bearing 1.25 tons, you see the bearing radial load of 1.25 tons on it

Q: Deep groove ball bearings 61805, 16005, 61905, 6005, these 4 bearings bore 25, how many are four figures, and some five figures?: The standard code for bearings is 6 - 61805, for example, 6 for deep groove ball bearings, 18 for outer diameter and width size series, and 05 for internal size series. The code for the zero series can be omitted, so my bearing code is 4 bits and 5 bits. Specific bearing coding and naming rules

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 have an inner diameter of 25 and an outer diameter of 47. How much is the tolerance of the shafts and jackets that match it?: What do you think you should do with it?.See what brand you use, the general use of NSK bearings.There are two kinds of thickness commonly used, one is 8, and the other is 12I think your bearing is generally used in interference fit (FIT) axis should be 25 deviation is under +0.021 bias is 0 on the 25 bearing diameter deviation is +0.048 error is +0.035 H7/s6 but normal bearing diameter using heat up method to cooperate. I hope you can absorb. Outside diameter 47, the upper deviation is +0.033, when the deviation is +0.017, the hole with the outer diameter 47 is the upper deviation is 0.025 H7/n6I hope you understand. I can't make myself clear on thisI'm using the base hole system. I don't understand this one. I am a mechanical engineer

Q: What is the function of the bearing dimension series?: The width series, 0.1.2.3, represents different widths, such as deep groove ball bearings 6011, width 186211, width 216311, width 296411, width 33The diameters of series 00, 01, 02, and 03 indicate that the bore diameters of bearings are 10, 12, 15, 17., respectively

Q: In the new standard, deep groove ball bearing type code name is 6, but I often see 16 to start with deep groove ball bearing code, such as 16005, I don't know what this 16 finger meanIn the mechanical manual, 16005 and 6005 are the same in diameter and outer diameter, but the bearing width is different. I just don't understand. What do you mean by 16?Isn't there a width code in the bearing model? And most of the bearings in the introduction, only that 6 represents deep groove ball bearings, need not appear 16 this code. But I checked, someone said, "16" means deep groove ball bearings which can be subjected to greater axial force. I wonder if it is?: 6 and 16 are deep groove ball bearings code, the difference between the two is bearing width, that is, the thickness of the points, and the rest of the same size

Q: How is the deep groove ball bearing fixed?: Landlord or a body sketch it, this is not good answer. Generally speaking, the fixed outer ring or inner ring can not simultaneously fix the outer ring and the inner ring.

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?: The bearing clearance is negligible and almost negligible, which is where the accuracy is. Another point of view, if there is no gap bearing operation does not burn?

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.
