Ball Excursion and How It Is Prevented
Uniform spacing of the ball set in a rotating bearing is critical to bearing performance and life. After all, every ball bearing—except for full complement designs—includes a cage, which positions the balls at approximately equal intervals around the bearing raceway. In some applications, however, the cage experiences a catastrophic failure by getting torn apart by the ball-set.
Such a… Read more
