- Q:What does 7 represent? What does the rest represent? If 7 is changed into other numbers, what does it represent?
- M stands for BrassIf 7 replaced by other figures, it is not a complete bearing model, if 7 replaced the suffix of the letter should be replacedSKF bearings are now too many fakes, you can try to use the Taiwan ZNQ, can replace imported bearings
- Q:In addition there is no other original bearing high speed bearing deposit in 50 seconds or more for the name?
- This is bound to have a lot, you can refer to the bearing of a book, can be used for industrial bearings, FAG, SKF, NSK and so on imported bearings, regardless of speed or accuracy requirements, the total requirements of wear one for you.
- Q:Feroform what bearing material, metal or nylon, or anything else?
- Stand erect, stand firm, stand erect, erect, written, erect, erect
- Q:Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?
- GY6 pedal motorcycle, in addition to the crankshaft on the right side of the starting driven gear, there is a reverse Taiwan screws, other screws include the front fork, each screw is thread.
- Q:when the ball bearings bear the equivalent dynamic load doubled, how will the bearing life changes? When other conditions are constant, how will the life of the bearing change when the speed of the ball bearing is doubled?
- The dynamic load increase or decrease is not the main reason for the bearing's life, so far there is no specific formula can be called out and life ratio, the main reason is that determines the life, life = rated speed * * unit unit time temperature / time * temperature value is not completely accurate, anyway and environment. The temperature, the length of time, there is relationship between static and dynamic load!
- Q:What about the other workshops? Yes, I have a share in it. Which workshop is better in Changzhou?,
- Which shop is tired, hard work, see how you do, I hope you can help
- Q:SKF bearing samples provide full set of SKF bearing samples, and other brand samples
- This specific or contact their company is more appropriate
- Q:Bearings radial, in addition to the location of contact with the box, there is no other way?
- 10, to prevent the bearing in axial load axial movement, bearings on the shaft and outside the Nanning hole are applied axial positioning device. Bearings on the shaft and the selection of the location of the shell depends on the size and direction of the load on the shaft, the speed of the bearing, the type of bearing, the position of the bearing on the shaft, etc.. The higher the axial load, the higher the bearing speed, the more reliable the axial alignment. For different types of bearings, axial positioning should also be different. Such as diagonal contact ball bearings and tapered roller bearings, shoulder and shell holes can be used to shoulder one-way support, without the use of special positioning device, the ring in the axial movement can be supported by the bearing itself. As a fixed support radial bearing, the inner and outer rings are fixed on the left support in the axial direction. As a traveling support that needs to compensate for the thermal elongation of the shaft, if a separable bearing is not installed, only one of the rings needs to be fixed, and the traveling ring is not fixed. Separate bearings, such as short cylindrical roller bearings and needle roller bearings, are installed in the traveling support, and all two rings need to be fixed. Bearing bearing ring used to positioning method is described as follows: 1. the bearing inner ring mounted on the shaft bearing inner ring, generally by the shaft in a fixed bearing position, and the other side with nuts and washers or spring retainer ring fixed.
- Q:The car separation bearing is broken, isn't it? What's the cause of the other broken bearings?
- Judging the quality of the separation of bearings: step down the clutch pedal to half linkage position, and then make a noise, you can judge the separation of bearing damage
- Q:Must the axle neck fit with the bearings? Is there anything else you can use? Or nothing?
- The rotating part of the supporting shaft must have a bearing, either a rolling bearing or a sliding bearing.
