Do you know how a ball bearing works? The load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it to spin smoothly.
Q: How do I go about checking for blocked or gummed-up tubing in my air conditioning unit’s motor? A: Simply replace the tubing, or use an air compressor to send some air through.
Under normal operation, the temperature of bearings will rise with start up and then stabilize at a slightly lower temperature within a specific time frame. The time before stabilizing will depend on the size, type, speed, and lubrication system of the bearing.
Choosing a new pump? Lower cost and under-sized components tend to cost you more in the long run. Some consume up to 30% more in power, and because they often run hotter, performance declines and repair costs climb.
Bearings use materials that are common in other household items. For example, polytetrafluoroethylene, or PTFE, is used in bearings, but it is also what makes pots and pans nonstick.
Checking your motor’s capacitors is important. How? Take off the start capacitor, make sure there isn’t any fluid, and set a volt meter to 1k ohms. Then, touch both terminals with your meter test leads.
