Running a pump dry will not damage the motor bearings at all. It is the pump seal that gets damaged. Some of the more modern pumps have enough water in them to allow the pump to run dry for quite a long time before seal damage occurs. It is the heat build up from the friction on the seal that causes failure. If you have run your pump dry and see any leakage at all, replace the seal immediately. The leaking water may "crawl" up the motor shaft and that is what will damage the motor bearings.
