INA bearing lubricant's main purpose is to decrease the friction and wear of each component. To a thin layer of lubricant oil film separates the scrolling and sliding surfaces, running performance and service life of INA bearings lubrication system and largely depends on the adaptability of lubricants on applications, function of lubrication in bearings are:
1, lubrication of friction surface:
1} reduces rolling friction between the rolling elements and raceways, increase the service life of INA bearing, cost savings.
2) INA bearing roller end sliding friction with guide flanges to avoid causing friction roller and flanges, cause bearing not rotate so that rupture of the bearing.
3) sliding frictions between the rolling elements and cage
4) roll cage and sliding frictions between the road surface of the boot
2, originating from outside the system by friction and the heat produced by the energy transfer, thermal transfer function is an example of circulating lubrication systems in effect for high speed applications.
3, dust-proof and rust
1) prevent substances into bearings
2) corrosion prevention of bearing parts
4, the concentrated stress release
1) on rolling contact surface stress in uniform distribution
2) mitigate the impact load
Considerations for lubrication
1) in diameter to maintain adequate lubricant on friction surface membrane separation
2) requested on the contact surface of the oil film is heat-weakened, you must maintain sufficient oil viscosity
3) tends to deterioration due to lubricants with temperature rise, INA bearing application designed to maintain the lowest possible operating temperature
4) lubrication system must be suitable for applications, lubricants and compare the performance of virtual has suitable
5) lubricants must be kept clean, even small undetectable to the naked eye magazine
