Bearing Life Product Calculator | AST Bearings

The L 10 Basic Rating Life is the estimated fatigue life of a large population of such bearings under the specified loading. It is assumed that the bearings have normal internal radial clearance, they are handled & mounted properly, and there is no misalignment, no excessive heat, or contamination in the bearings.

» Industrial gearbox design has come a long way

Feb 15, 1995· As the gearbox is equipped with deep groove ball bearings, the various misalignments do not significantly affect bearing life (see figure 6) because the actual maximum values are far lower than the recommended limits for this type of bearing. In addition, bearing life is also influenced by the different load distribution over the rolling elements.

Technical Information: Ball bearing types, selection

Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.
