  • How do radial vs. thrust loads affect ball bearing selection?

    2021-4-5 · if you look at a ball bearing in cross-section, you will see that the balls are assembled into the two races in such a way that the races have side walls against which the balls can press as they roll. this means that a thrust load on one race will be transmitted through the balls to the opposite race without tending to push the races apart and open up the bearing. note that to …

  • What does it mean that a ball bearing can handle thrust ...

    Thrust load capacity varies dramatically with design. The grooves in the races of the deep groove ball bearing permit the transfer of moderate thrust in combination with radial load. The angular contact bearing (Figure 6.1(f)) is better than the single row ball bearing, because the races are higher on one side providing a more favorable load ...
