63 Series of ball bearing,deep groove ball bearings

Q: How are the parts assembled together for deep groove ball bearings?: Deep groove ball bearings are composed of inner ring, outer ring, steel ball, upper and lower cage.Assembly sequence: the outer ring shall be fitted with inner ring, the cage, the steel ball, the other cage, and finally the rivet (hole on the cage).

Q: Deep groove ball bearing 629Z code, how to resolve?: 6 model code for deep groove ball, 2 diameter code 9, internal diameter of 9MM, -Z iron cover

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: Deep groove ball bearings 61805, 16005, 61905, 6005, these 4 bearings bore 25, how many are four figures, and some five figures?: The series is not the same, after the general bearing type bearing diameter is multiplied by five

Q: A deep groove ball bearing model with an outer diameter of 8.5 cm and an inner diameter of 4.5 cm: A deep groove ball bearing model with an outer diameter of 8.5 cm and an inner diameter of 4.5 cm is 6209

Q: What are deep groove ball bearings suitable for automotive parts?: The characteristics of this bearing is suitable for a wide range of shortcomings can not be used in large power equipment, the car using the bearing place or more, such as generator, water pump, air compressor, air blower, steering, transmission are used in the bearing.

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: 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?: Online summary of the next answer to you.At low temperatures, the viscosity of the lubricant is even frozen, and the system work load increases, resulting in poor lubrication and accelerated bearing damageObjects have the nature of expansion and contraction, bearing, bearing and the like.Material shrinkage is different, so that the structure deformation, stuck.One end of the shaft is mounted with a pair of cylindrical bearings positioned as a shaft,The axial movement of the axle is restrained, and the other end of the shaft is supported by rolling bearings only to the radial force,In the axial direction, it varies with temperature and moves axially in a certain range. Such a structure is better.Low temperature greasePhysical condition: semi fluid color: Brown odor: fat oilSolubility: soluble in most organic solvents, water soluble: insolubleUniway LIX 22 PA grease is a kind of grease based on poly alpha olefin oil and compounded with lithium soap as thickener.The grease has a wide temperature range, high drop point, high performance oxidation inhibitor, low base oil viscosity and low temperature resistance.

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?: As mentioned above, 16 is a thin walled bearing. As in the 68 series of 69 series, it belongs to the thin wall bearing.

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.
