I tend to believe that there must be a bending component in the forces, granted that it must be very small compared to the shear. Even a small bending component would have a substantial effect on the fatigue life. Its my understanding that its not the blocking ring as you call it, that fails but rather the hub over which it slides. cheers, Steve Cotsford Columbia SC |
