- 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: Isn't it the middle question or the other question? I'm looking for glfore to do the test. Did anyone do that?
- Possible in the middle. There may be other problems. You can try with them. Excellent
- 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: What's the bearing fillet of the 7003C? Do other bearings have the same fillet?
- In GB/T292-1994 standard, the fillet of 7003C is r0.15 to r0.3; in GB/T292-2007 standard, the fillet of 7003C is r0.10 ~ r0.3.
- Q: 22318CA are there any other bearings that can be used instead?
- If it is imported, it can be replaced by domestic product. However, there are still some differences between the quality and the import. It depends on what equipment you use.
- Q: 1.6 of the two case K2 rear wheel bearings are the same as the other K2?
- I would like to ask whether you have seen bearing down bearing types and brands, if we can determine the type and the brand can determine the price, in addition to bearing high precision machinery products, try not to buy Taobao, best buy through formal channels....
- Q: Machine specific, please describe the specific points
- Many types of bearings. According to the direction of the load it can withstand can be divided into: the radial bearing, also known as radial bearings, bearing radial load. The thrust bearing, and thrust bearing, bear the axial load. The radial thrust bearing, also called centripetal thrust bearing under radial load and axial load at the same time according to the nature of work. The friction bearing can be divided into different sliding friction bearings (the sliding bearing) and rolling friction bearings (the rolling bearing) two categories.Angular contact bearings: ball and raceway nominal contact angle greater than 0 degrees, the rolling bearing and less than 90 degrees. At the same time can bear radial load and axial load. Can work at a higher speed. The larger the contact angle, the axial bearing capacity is higher. The high precision and high speed bearings usually take 15 degrees contact angle in the axial direction. Under the action of force, will increase the contact angle. The axial load of ball bearings can only bear a direction, in radial load, will cause additional axial force. The axial displacement and can limit shaft or shell in one direction. If the duplex mounting, so that a pair of bearing outer ring relatively, i.e. the wide end of the wide end, the narrow end face with narrow end. So to avoid the additional axial force, but also in the two direction of the shaft or shell limit in the axial clearance range.
- Q: In bearings, why are the flanges connecting the upper and lower cases higher than those of the other bearings?
- If it is understood as the reducer, the upper and lower box connecting the flange (bearing box outside the prominent part), the reason is to prevent the bearings in operation, gear and box friction, damage box, reduce gear life.
- Q: In addition to NSK and KOYO, what are the other four major bearing producers in Japan?
- NSK in Japan bearing is the largest share of the domestic market after the Swedish SKF, NTN and Koyo other than NSK.
- Q: why the inner ring of a knock on the broken, and other small manufacturers desperately not broken, is the material problems or other reasons? The hardness is about the same. LYC62 another 63. How can this be explained? Seek expert advice!
- You may have this bearingImitationThe hardness is not too high,High imitation is the quality of the bad ah!
