What is the noun explanation of bearing life and the standard for measuring bearing life
Under a certain load, the number of revolutions or hours experienced by the bearing before pitting is called the bearing life.

Many, most of the damage reasons of NSK bearings is like than previously estimated the load, the effective sealing, tight is too small, as a result of the common bearing clearance, and so on.
There is in any of these factors factors the extraordinary damage type and leaves the extraordinary damage part.
Examine damaged shaft bearing, therefore, in most cases can invent its about the result.
General speaking, a third of the bearing damage resulting from the fatigue damage, a third of the other resulting from poor lubrication, a third of the other resulting from pollutants enter the bearing or punish improper installation processing.
However, these also related to property don't damage types.
Parables, pulp and paper fortune most half is due to bad lubrication bearing damage or contamination is not due to material fatigue.
Bearing the axial bearing capacity limit: 1, bearing such as under pure axial load, the axial load is generally should not be more than the value of 0, 5 C0.
2, small bearings (
In 12 mm diameter)
And light series bearing (
Diameter series 8, 9, 0 and 1)
Should not be greater than 0, 25 C0 under axial load.
3, axial load is too big, can greatly shorten the service life of bearing.
4, if NSK bearings under certain radial load, also can withstand the axial load limit?
Normally if the bearing can bear radial load, also can absorb a certain amount of axial load.
