conversations.value: Roupeda: Floating bearing, in the harsh environment use sealing bearing ring and extend the service life of bearing seal cover can prevent invasion of sewage because of meaning. Roll in roller mill usually irregular four child bearing seal ray fall to the ground. When using that the impact of the strong men, water and debris intrusion.
  Japan NSK company development at the beginning of the sealing roller clean easily. Wood this bearing is cruel lubrication bearing foundation condition, improved the accident quantity 34%, the life of the high reliability, easy to remain the same. This performance optimization is to improve mechanical design patent technology, new materials and sealing results. Compared to traditional wooden roller bearing, the sealing roller bearing wood basic rated men, not only 2 34% live longer. Seven times. Roller clean seal bearing capacity of wood properties like at the beginning of the second element, adopt NSK company manufacture super - tf bearing strength. Solve the material or lubrication bearing life under the condition of inadequate pollution problem. Experience, under the condition of pollution start splinters of bearing is pollution. NSK company based pollution or edge of the lubrication conditions, whether through the bearing life improvement of bearing steel microstructure. New sealed structure is given priority to seal and seal. Ball of negative pressure water is in airtight princess intrusion, the seal negative pressure a lot of things. Accordingly, reduce the negative in the bearing to prevent water pressure into the basic. Is the most effective method of sealing ball inherent skills airtight direct contact with the water retention, water is sewage and prevent the wood on the side. Airtight way instead of contact wire surface in contact, whether to stop all operation process, the ball surface contact sealing good sealing characteristics. Therefore, a new second capacity than the bearing roller clean seal with the traditional wood sealing roller bearing general credibility. Lower bearing adjustment orbit sound 
  In addition SKF Italy airtight company (recently developed) sealing the next generation of oil and local mud block. He optimal design of closed structure to prevent the invasion of mud indeed. Outside the traditional sealing structure is radial lip and seal diameter and left circle between tension and fixed sealing prince circles. New structure is the bushing sealing and into a ring sealing ring plate, from the appearance and bushing inside diameter, my lips with a waterproof encouraging local, observe the product. According to the operation requirements and application conditions of mud block can be used all kinds of elastic material. In this material, acrylic acrylic congregate, star rubber fluoride etc.
