Deep groove Ball Bearings
Description: Deep groove ball bearings are the most common type of rolling bearings, the basic model deep groove ball bearing consists of an outer ring, an inner ring, a ball and a group holding structure into. Deep groove ball bearing has two types’ kinds of single and double row, the structure of deep groove ball is also divided into two structures sealed and opened. Open means bearing without seals, sealed deep groove ball is into dust seal and anti-oil seal. Dust sealed cover for high-quality steel stamping, Play a supervisory anti-dust into the bearing raceway, type Anti-oil is contact seal，Can effectively prevent grease spills within the bearing.
works:
Deep groove ball bearings mainly take radial load, Also radial and axial load，When the only radial load，contact angle is zero，When the deep groove ball bearings with a larger radial load，Have a contact angle of bearing performance，Can withstand greater axial load，Deep groove ball bearing friction coefficient is small，and speed is also high.
Features:
Deep groove ball bearings are the most representative of the rolling bearing, and versatile. For high speed or high speed operation, and very durable, regular maintenance. This kind of bearing friction small number, This kind of bearing friction small number, Extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse, used in precision instruments, Low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of bearings.
F&Q
Q:How long es cycle of bearing life?
A:According to international standards, at least a year and a half , up tu 3 years
Q:How to maintenance bearing
A:Add to lubricantes on time
Q:Have diagram for bearing
A:The small one no have, large bearings will provide diagram
- Q: What are the dimensional tolerances for deep groove ball bearings?
- 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.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: 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: If you do not have this specification, there are similar, please say, and, incidentally, with the approximate specifications, thank you!
- Internal diameter 8MM, outer diameter 22MM, width 14MM, double row ball bearing, Wuxi one male bearing
- Q: I use a deep groove ball bearing now, model is GB/T 276-1994, a large diameter 90, 50 paths, 20 thickness, requirements of bearing outer ring arranged on a bearing seat fit, the inner ring is mounted on a rotating shaft, and the fit, I don't know how to choose the tolerance than the more appropriate. The outer ring with which to choose tolerance, inner and choose? Please expert pointing
- Bearings are generally bearings and holes transition or gap, the use of special use of interference, if the choice of interference, the bearing holes selected N7, P7, axis selected N6, P6, hole tolerance increased level. Upstairs K7 is a transition fit, but also can choose, in general, if the requirements are not high accuracy, you can use the bearings and holes transition coordination.
- 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: 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: 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).
- Tolerance standards refer to GB/T307.1-2005, divided into 0, 6, 5, 4, 2, five precision levels
- 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?
- Deep groove ball bearingThe most representative rolling bearings, wide range of usesCan bear radial load and two-way axial loadIt is suitable for high speed rotating and low noise and low vibrationSealed bearing with steel plate dust cover or rubber sealing ring is filled with proper grease in advanceThe outer ring with a stop ring or flange bearings, that is easy to axial positioning, and easy to install inside the housingThe size of the maximum load type bearing is the same as that of the standard bearing, but there is a loading groove in the inner and outer rings, which increases the number of balls loaded and improves the rated loadMain retainer: steel plate holder (waveform, crown)... Single row; S shape... Double column)Copper alloy or phenolic resin cutting cage, synthetic resin forming cageMain application: Automobile: rear wheel, transmission, electrical partsElectric: General Motors, household appliancesOther: instrumentation, internal combustion engines, construction machinery, railway vehicles, handling machinery, agricultural machinery, various industrial machinery
- Q: The difference between deep groove ball bearings and thrust ball bearings
- Deep groove ball bearings bear radial load and thrust ball bearings bear axial load
