IKO roller bearing fatigue, noise, how long is the life of a respective lubrication

Fatigue life of IKO bearing operation process, absorb a certain amount of load, even if is the static load, but for steel ball and raceway, the stress is a cycle, the material will be rolling fatigue so that imported bearing to life. The phenomenon as part of the rolling surface materials like fish scales suddenly fall off, this phenomenon is called fatigue spalling ( 剥落) 。 Noise life of household appliances bearing, roller bearing load is small, has a long bearing life. But bearing operation after a period of time, will also generate wear, vibration noise increases, grease degradation, etc. Due to strict in home appliance bearing noise, when IKO bearing noise beyond the allowable range, consider bearing cannot continue to use. Roller bearings with low noise the total time of operation is called noise bearing life. Household appliances IKO bearing lubrication life usually adopt grease maintenance-free sealed bearing. Although roller bearing lubrication need only tiny amounts of lubricant, but after running a long time due to the deterioration of the grease and leakage, poor lubrication bearing, roller bearing failure. Good bearing lubrication condition the total time of operation is called bearing life. For light load bearing, roller bearing noise life and lubrication life shorter than the bearing fatigue life. Such as home appliances bearing, as long as the IKO bearing selection and installation is correct, can satisfy completely the requirements of the life of the host matching.
