Flow if NSK bearing used in harsh environments, bearing seals and the seal cover is essential, as they can prevent the intrusion of contaminants to extend bearing life. Rolling mill roll typically consists of four rows of NSK sealed tapered roller bearing support. Use requirements when subjected to a strong impact load, the intrusion of water and debris.
Company NSK cleaning roller neck bearings of the super easy sealing. Lubrication of these bearings in the harsh conditions, the amount of load increase by 34%, and high reliability, long life, easy to maintain. This performance improvement is the optimization of the mechanical design, the use of new materials and patented results of sealing technology. Compared with the traditional roll neck bearings, this sealed journal bearing not only the basic dynamic load rating by 34%, and extended life span of 2.7 times. Ultra-seal cleaning roller journal bearings performance improvement of capacity the second factor is the adoption of the company developed the Super-TF bearing steel. Settled in this material under the condition of pollution or inadequate lubrication of NSK bearing service life. Experience has shown that pollution under operating conditions, NSK bearings are vulnerable to intrusion of debris and pollution.
Company′s research has shown that in the NSK bearing life under contaminated lubrication conditions or edge through improving the micro-structure of bearing steel increased. New sealing structure of seals and holes sealed. NSK bearings produced in negative pressure can cause intrusion of water from the main seal, pore sealing structure has a great impact on negative pressure.
Therefore, reduction of negative pressure in NSK bearing are basic requirements to prevent water entering. The most effective method is to keep hole sealing from direct contact with water, seal original while retaining the bore feature?? Prevent the intrusion of water and dirt from the side of the neck. Sealing method using surface contact instead of a line contact, whether it′s running processes, or static process, surface contact hole sealed with good sealing characteristics. Therefore, the new super capacity seal cleaning roller neck seal journal NSK bearings NSK bearings than the traditional with higher reliability
