Q: What does "6208" in deep groove ball bearing 6208 GB/T 276-1994 mean? Ask God for detailed explanation and dimensional description.: 6208, the spot price is 7 yuan a setBearing series: deep groove ball bearingsInside diameter: 40mmOutside diameter: 80mmThickness: 18mm

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: Deep groove ball bearings, iron cap seals and rubber cover seals are distinguished?: Use bearing rubber cover for dust and sealing can be waterproof, but the friction is larger, but the speed is low and the iron iron cover; cover the main role is to dust. The iron cover high speed, but because of iron, so it is not waterproof.

Q: Do deep groove ball bearings come with a top wire?: What's the effect of your top wire? As far as I can understand, only the bearing unit with top wire is used to fix the outer ring of the bearing on the bearing seat

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 are also called ball bearings: The rolling bearings can be divided into ball bearings and roller bearings according to the shape of the rolling bodiesBall bearings, also known as ball bearings, deep groove ball bearings, is a kind of ball bearings

Q: Deep groove ball bearings 61805, 16005, 61905, 6005, these 4 bearings bore 25, how many are four figures, and some five figures?: Although the diameter is the same, but the width, diameter is not the same.For example, 18 year old beauty, some fat, some thin.I can also give you several sizes of bearings with an inner diameter of 25,62056305 are deep groove ball bearings

Q: What is the width tolerance of the 6 degree deep groove ball bearing B?: This depends on the size of the bearings, sizes, tolerances are also different. You can use the Internet to find national standards and are generally free to download. If you need to know the value of the specific dimension tolerance, please tell me the size of the bearing. There are various bearings factory standards are generally smaller than the national standards, that is, more stringent than the national standards. So, mainly depends on what brand you are bearing!

Q: 6207, deep groove ball bearings can withstand the axial force of how much?: Under this kind of force condition, it is better to use the opposite angle contact. The deep groove ball is mainly radial, and the axial direction is not the main direction of force. Plus this size and speed, the 7207 is the best fit

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.
