INA bearing seals larger than dust cover, and be flexible and lower-speed scroll of a scroll limit. When designers in selecting appropriate seals, must consider the function and distribution of lubricants and expectation of the working premises of the system.
INA bearings in use very strong to withstand high loads, shock, rust and water and dust intrusion, INA developed a novel ultra high load-carrying capacity of the bearing seal and clean lubrication bearings. It is said that this can increase the 34% of bearing load capacity, and with higher reliability, can work long hours under poor lubrication provided. INA bearing function after improved sealing, combining optimized mechanical design, materials and sealing patent, installed and easy to manipulate.
Common seal INA bearings, seals and width limits the length of the roller, which limited the load carrying capacity of the bearing. Therefore, in the design of their new INA bearing, are contained in a sealed cage document open-free, enables the long roller, roll cage diameter increased and lengthened, while cage length is increased, reaches higher 34% Basic rated load capacity, commensurate to extend 27 times INA bearing life. The quality of bearing selection "T-F" bearing steel, is also improving the function of bearing hub, due to impurities in the material and lubrication INA bearing caused by uneven is the main cause of premature failure.
Experience has shown that pollution in work context, INA bearing into the debris, and the detrital particles can damage the roller, resulting in stress concentration. In addition, if lubrication is not average, metal surface hard contact, resulting in tiny "peeling" damage can also cause contact areas of stress concentration, both results cause stress concentration area of the sub surface cracking of metal and ultimately shorten the INA bearing
