For current SKF bearings; the extra lifespan of SKF bearings may be quite different from the actual service life in a particular application. Pollution levels, misalignment, correctness of equipment, smoothness and environmental factors, etc. It is the use of life is affected by a variety of different factors. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
ISO 281:1990/Amd2:2000 promises the bearing manufacturer to recommend the appropriate method; to calculate the available bearing life correction coefficient according to the operating conditions. SKF bearing additional correction coefficient aSKF adopts the concept of fatigue load limit Pu; similarly used for other machine parts The algorithm. The value of the fatigue load limit is shown in the product list. In addition, the SKF bearing extra life number correction coefficient aSKF also uses the smoothness and pollution degree coefficient ηc to reflect the operating conditions in operation. ISO281:1990/Amd2:2000 It contains a modified life equation to compensate for the extra extra life of SKF bearings. This life-cycle algorithm uses a correction factor; it can also calculate the bearing's smoothness, pollution and data fatigue limit.
