 Bearing life: in a certain load, bearing in revolutions or hours before pitting experience, which is called the bearing life. Rolling of life in revolutions (or the number of hours of work under a certain speed) Definition: In this life within the bearing should happen preliminary fatigue damage (flaking or chipping) any bearing on their laps or rolling elements. However, both in laboratory tests or in actual use, can clearly see, the appearance in the same working conditions of the same bearing, the actual life different. In addition, there are several different definitions of bearing "life" of spherical cylindrical roller bearings, one of the so-called "working life", which represents the actual life of a bearing before the damage can be achieved by wear, damage is usually not by fatigue due to the inner cylindrical roller bearings, but is caused by wear and tear, corrosion, seal damage and other reasons. In order to determine the standard bearing life, the bearing life and reliability linked. Due to manufacturing precision cylindrical roller bearings, the uniformity of the material differences, even the same material, the same group of the same size bearings, used under the same operating conditions, their life is not the same length. In terms of statistical life expectancy of a unit, the longest life expectancy of 4 units relative shortest 0.1-0.2 units of multi-row cylindrical roller bearings, the longest and shortest life expectancy of more than 20 to 40 times. 90% of the bearing does not produce pitting, revolutions or the number of hours after which called Bearing rated life. 1, only slightly higher than the starting rotation friction torque friction torque; 2, sensitivity to variation in load bearing deformation is less than the hydrodynamic bearing; 3, only a small amount of lubricant will be able to function properly, the runtime can provide long lubricant ; 4, the axial dimension smaller than the conventional hydrodynamic bearing; 5, can support a combination of radial and thrust loads; 6, to a great load - within a speed range, the unique design can achieve excellent performance; 7, bearing performance on load, speed and running speed fluctuation is relatively insensitive.
