- Q:What's the other size of the outer diameter 15?
- First of all, the outer diameter of 15 bearings, bearings, several kinds, such as deep groove ball bearings, needle roller bearings, cylindrical roller bearings, tapered roller bearings, and so on, followed by. Bearing bore is not the same, in addition, the bearing width is not the same. You can refer to the third edition of the mechanical manual
- Q:What's the bearing fillet of the 7003C? Do other bearings have the same fillet?
- The other bearings don't have the same fillet, and the bigger the bearing, the bigger the fillet.
- Q:Feroform what bearing material, metal or nylon, or anything else?
- It's made of toughened and wear-resistant nylon, which is more high-grade. As bearings, there are generally PA66+30GF/CF, PA66+PTFE+GF/CF, PA66+, molybdenum disulfide, of which the most cost-effective is PA66+ molybdenum disulfide. Our company has production, and if necessary, you can contact me.
- Q:I need regular manufacturers' agents (with authorized certificates and large scale agents)
- I am Nanjing Yi million strong bearing Co., Ltd. (Jiangyin Office)I am mainly responsible for regional sales in Jiangyin, Zhangjiagang, Jingjiang and so onWe are regular dealers. Here are our certificate of authorization.
- Q:Why are the front fork bearings of the GY6 so difficult to buy, smaller than others?
- if the big nut steering column, in the absence of special sleeve case, can use spanner or hook wrench assembly.
- 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:Bearing, in addition to interference, excessive, gap three kinds of co-ordination, there are no other coordination?
- These three types of coordination, and other coordination is only a different individual name, but the actual situation is the same
- Q:Compared with other bearings, what is the application performance of NSK Bearings?
- The quality of NSK bearings and all aspects are good, after all, is a big brand!
- Q:In engineering practice, for needle roller bearings, usually axial positioning is the same as other bearings?
- Needle bearing features are axial can not bear the load, so the operation of the axial direction of the bearing no force, radial installation slightly tight can be, the axial need not limit
- Q:Yoyo how can I wash the bearings without gas?. What other materials can I use?
- Thinner, acetone, chloroform, banana water, kerosene.
