What is Bearing (mechanical)?
[[Image:Four-point-contact-bearing din628 type-qj 120-ex.png|thumb|Radial ball bearing]] A '''bearing''' is a device to permit fixed direction [[motion (physics)|motion]] between two parts, typically [[rotation]] or linear [[movement]]. Bearings may be broadly grouped by the way they work. The most common of the many types are [[plain bearing]]s and [[rolling-element bearing]]s. The two main types of rolling-element bearings are ball bearings and roller bearings. In ball bearings, the rolling elements are spherical balls. In roller bearings, the rolling elements are cylindrical, taper or spherical rollers. Ball bearings are shown in the pictures. == Other websites == {{commonscat|Bearings}} [[Image:BallBearing.gif|thumb|upright|[[Ball bearing ]]]] * [http://www.msm.cam.ac.uk/phase-trans/2011/Bearings/index.html Comprehensive article on bearings] {{Webarchive|url=https://web.archive.org/web/20160123062144/http://www.msm.cam.ac.uk/phase-trans/2011/Bearings/index.html |date=2016-01-23 }} *[http://science.howstuffworks.com/bearing.htm How Bearings Work] - Animations and functioning * [http://www.mechanismen.be/mechanismen/lagers/losse-vaste-passing/lagers-losse-vaste-passing-01.htm How Bearings Work - ] - Animations on www.mechanismen.be * [http://www.reliableplant.com/article.asp?articleid=260 Early Bearing Failure Detection] {{Webarchive|url=https://web.archive.org/web/20080208101730/http://www.reliableplant.com/article.asp?articleid=260 |date=2008-02-08 }} - Case study * [http://www.boschrexroth.com/redirect?coid=9466 Catalogs, CAD files and more Bearings information from Bosch Rexroth]{{Dead link|date=December 2022 |bot=InternetArchiveBot |fix-attempted=yes }} [[Category:Mechanical engineering]]
