Preventive maintenance of TIMKEN cross roller bearing service life

For TIMKEN cross roller bearing equipment preventive maintenance, operation and peripheral parts change was removed when the suspension bearing checking, discriminant times demand, in turn, TIMKEN can cross roller bearing parts can be used again and record the condition of using good from bad. Second bearing raceway surface of the rolling surface and on the surface of the joint venture and confrontation of the wear conditions of with and without damage and abnormalities in particular is to examine the raceway surface running track. Discriminant TIMKEN cross roller bearings can use again, to ponder on the level of the bearing damage, mechanical function, primacy, operation premise, such as checking cycle back again choice. Checking the effect, if found damage and abnormalities in TIMKEN cross roller bearing, please find out notice according to the bearing damage phenomena, develop countermeasures. In addition, the checking result, there are some defects, if the bearing can't use, need to change the new bearing. Floating bearing if used in harsh environment, bearing seal and seal cover is indispensable, because they can prevent dirt intrusion, extend the life of the bearing. In mill roll usually by TIMKEN cross roller bearing support. When using requirements under strong impact load, the intrusion of water and debris. Bearing of negative pressure can result in water from the main sealing intrusion, hole sealing structure has a great influence on the negative pressure. Reduce the negative pressure in the TIMKEN cross roller bearing, therefore, is to prevent the water into the basic requirements. The most effective way is to make the hole sealing no direct contact with water, while retaining the original function - hole sealing — To prevent water and dirt intrusion from roll neck side. Sealing methods for line contact surface contact, whether it's running process, or stationary process, surface contact hole sealing are characterized by the good sealing. Therefore, the new super clean seal bearing capacity than the traditional sealed bearing has higher reliability. Bearing lubrication in harsh conditions, load volume increased by 34%, and high reliability, long life and easy maintenance. This improvement is to optimize the performance of mechanical design, using new materials and patent the results of the sealing technology. Compared with the traditional TIMKEN cross roller bearing, this kind of TIMKEN cross roller bearing is not only the basic dynamic load rating increased by 34%, a longer life expectancy and 2. Seven times.
