Q: What kinds of seals are there in SKF bearings?: The 3. axis supporting structure has the advantage of allowing angular deviation;4. circumferential velocity of sealing surface;5. the working temperature of the bearing;6. manufacturing costs.

Q: What are the seals commonly used in the industry?: In recent years, the production and quality of rubber seal products in China have gradually entered a new stage and new period. However, only these can not satisfy the need of the development of other industries of various types of rubber seal products standardization and serialization of products, especially compared with the international advanced countries, our products in terms of product quality, or product varieties, has a considerable gap. The 100 forum focuses on the concept, seal the research content and research significance, summarizes the current situation of rubber seal, mechanical seal and packing seal technology, analysis of China's and the world advanced sealing technology in developed countries at the level of research and development ability of the new products on the gap, and our future focus on the seal the field of research and put forward some suggestions.The overall competitiveness of China's sealing industry is not strongAs we all know, in our country, the sealing industry can be regarded as the smallest industry, but the products can be used in conjunction with large industries. No matter aviation, navigation, petroleum, chemical industry, or machinery, power generation, metallurgy, mines, etc., are inseparable from the seals. In short, all organic, pump, pipe, valve places are dependent on the seal. Therefore, the industry is small, involving a wide range of faces.

Q: What's the difference between an oil seal and a seal? Is it the same thing?: The seal is a general term for all products that are sealed. They include O rings, oil seals, seals for piston hydraulic cylinders, dust rings, and so on,

Q: How can the tapered roller bearings be sealed?: The seal can prevent the loss of lubricant and dirt into the SKF tapered roller bearings, thereby maintaining SKF lubrication of tapered roller bearings and the clean degree and is conducive to the achievement of long life, but also to consider the effectiveness, cost, simplified sealing sealing structure and effective period, according to the SKF tapered roller bearing environmental conditions and requirements of life to be a reasonable choice

Q: There are two types of oil tank seals for transformers. They are "totally sealed" and "oil pillow type". What is the difference between them? Who can explain in detail?: The seal type of transformer is oil pillow type.Reasons for leakage of transformer oil:1, general seals are life, because the seal is made of rubber materials, rubber in the environment will gradually aging, the aging of rubber lose their elasticity, also lost its sealing performance. My experience is that the life of a general rubber seal is 3-5 years.

Q: What's the difference between the oil seal and the seal?: Skeleton oil seal, TC import oil seal and domestic oil seal, the main difference has the following key places, materials, imported oil seal material and formula used to produce the product quality is better than the current domestic oil seal

Q: You want to ask knowledgeable friends. I want to do at home produced small seal factory. The former is to buy it do seal butterfly valve. Now they want to engage in their own ring. Do not know what equipment and capital equipment. Then buy new and used funds is how much. Is the production of multi-level sealing ring and PTFE. What materials should I indebted forever: These two are completely different materials, the rubber ring is generally rubber, PTFE is plastic, the production process is not the same. Not familiar with, or first learn more professional knowledge!

Q: Men's motorcycle front left shock absorber oil leakage, do not change two seals?: Generally, there is only one oil seal, in the middle part of the shock absorber, the inner pipe and the outer pipe,

Q: What is the maximum resistance to the seal in the hydraulic system currently being produced?: The key depends on your seal structure, the good sealing structure can assist the seal, reduce the pressure of the seal. Take a simple example: the well-known O ring, the static sealing pressure 5~10MPa

Q: What are the better domestic rubber parts, seals ah, the best quality is better, cost-effective points: Basically close to the import price. We use another Bello new material technology, the price is much than in tophere
