... high-speed rotor test specimen was used to characterize the performance of two epoxy tow-pregs and three fibers, T-650-42, IM7, and M46J. Nagy et al. ( Ref 8.27 ) used a molybdenum-disulfide-filled nylon as the hub material, which then radially mass loaded the ring as well as the centrifugal forces due...

... of powder metal (PM) plain bearings may still be the most widely used bearing for fractional horsepower motors. It is not wrong to always consider this option for every bearing application. If motor speeds are above 3000 rpm, then it may be an inappropriate choice. Similarly, if the loads are very high...
