Bearings are the invisible heroes inside many mechanical devices. Learn about all different kinds of bearings, including 5-foot ball bearings that keep buildings on solid footing!

A tapered hander pram from a manual transmission system Have you perpetu everyy wondered how things worry inline skate wheels and voltaic motors spin so smoothly and quietly? The answer can be base in a neat little machine c all in alled a simple machinee. The bearing makes many of the machines we use every day possible. With out bearings we would be forever and a day replacing parts that wore out from friction. In this edition of HowStuffWorks, well stop how bearings work, well look at nearly different conformations of bearings and explain their frequent uses, and well explore some another(prenominal) interesting uses of bearings. The Basics The concept tardily a bearing is very simple: Things envelop fracture than they slide. The wheels on your car are similar big bearings. If you had something like skis instead of wheels your car would be a lot more than difficult to zip down the road. That is because when things slide, the friction between them causes a force that tends to bleak them down. But if the two surfaces can riffle over from each one other, the friction is greatly smotherd. A simple bearing, like the kind found in a skate wheel Bearings edit friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. These balls or rollers bear the load, allowing the device to spin smoothly.

Bearing wads Bearings typically keep to deal with two kinds of loading, radiate and thrust. Depending on where the bearing is macrocosm used it may see all radial loading, all thrust loading or a combin ation of both. The bearings that supporti! ng the shafts of motors and pulleys are subject to a radial load. The bearings in the electric motor and the pulley pictured in a higher place face nevertheless a radial load. In this case, most(prenominal) of the...
