If half of all ACmotor failures are caused by bearing failure, almost 80 percent of these are caused by electrical damage to New bearing race. Viewed under a scanning electron microscope, a new bearing race wall has a smooth surface (Photo B). As the motor runs, a track eventually forms where the bearing ball contacts the wall.
Jan 08, 2019· At the speeds at which modern turning centers operate, even carbide centers would fail due to excess friction and heat at the center/center hole interface. The "live" ball /roller bearing center eliminates the sliding friction by allowing more pressure to be applied to the part center hole,transferring the rotation to the rolling elements in ...
