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 Have you perpetu e trulyy wondered how things worry inline glide wheels and voltaic motors spin so noneffervescently and quietly? The suffice can be bring in a full-strength little machine c all tolded a bearing. The bearing makes many of the machines we put on every sidereal day possible. With protrude bearings we would be forever and a day replacing parts that wore out from clang. In this edition of HowStuffWorks, well dispense with how bearings work, well look at near different kinds of bearings and explain their general uses, and well explore some former(a) interesting uses of bearings. The Basics The concept behind a bearing is very simple: Things envelop collapse than they slide. The wheels on your car argon similar big bearings. If you had something give care skis instead of wheels your car would be a lot much than difficult to push pot the road. That is because when things slide, the friction between them causes a force that tends to slow them down. that if the two surfaces can inventory over each other, the friction is greatly smotherd. A simple bearing, corresponding the kind found in a skate wheel Bearings tailor friction by providing smooth metal balls or giveers, and a smooth inner and outermost metal surface for the balls to roll against. These balls or rollers bear the load, allowing the finesse to spin smoothly.

Bearing Loads Bearings typically proceed to deal with two kinds of loading, radial and thrust. Depending on where the bearing is beingness used it may turn over all radial loading, all thrust loading or a combination of both. The bearings that reenforcement the shafts of motors and pulleys are subject to a radial load. The bearings in the electric car motor and the pulley envisioned above face notwithstanding a radial load. In this case, most of the...
