Line 1: A '''slide plate''' is ~~non~~a ~~rotational~~[[Linear-motion orbearing#Plain bearing\|linear bearing]] ~~such as~~that may be part of the [[expansion joint]]s of [[bridge]]s, high temperature horizontal [[Chimney\|ducts]] of [[water-tube boiler]]s and other [[Mechanical engineering\|mechanical]] or [[structural engineering]] applications. inIn each case one plate is fixed and the other slides on top as ~~espansion~~expansion or contraction ~~occur~~occurs. ~~The plate may be of [[Polytetrafluoroethylene\|Teflon]], [[Lubrite]] or even plain [[steel]] according to the application.~~ {{engineering-stub}}▼ The plates provide a surface with a low [[coefficient of friction]] which can be attached to a supporting structure. This combination provides support while simultaneously allowing an object to move (slide) freely along the supporting surface.<ref>[https://www.pipingtech.com/products/ptpcat/slideplate/index.html Piping Technology: Product Catalog], Piping Technology & Products, Inc.(retrieved 30 August 2010)</ref> The plate may be of [[polytetrafluoroethylene]] (PTFE),TEF-MET,<ref>{{Cite web\|url=https://www.sbs-bearings.com.sg/home/\|title = Singa Bearings Solutions \| German Bearing Engineering and Consulting}}</ref> [[Lubrite]]<ref>[https://www.usbfmi.com/lube1.htm Lubrite technologies]</ref> or [[steel]] according to the application. Multiple design variations are possible but the most common example of a slide plate (in structural applications) has glass-filled PTFE <ref>{{Cite web\|url=https://www.pipingtech.com/products/ptpcat/slideplate/ptfe.htm\|title=PTFE Slide Plate – Products \| Piping Tech}}</ref> bonded to a steel backing plate. In these applications a two-part system is used which has an upper element with stainless steel surface face-down and bearing on a lower element with its PTFE steel backing surface face-up.<ref>{{Cite web\|url=https://www.sbs-bearings.com.sg/products/detail/mode/detailView/product/Flachstuetzlager/\|title=Singa Bearings Solutions \| German Bearing Engineering and Consulting}}</ref> In most applications, the upper element is larger than the lower element by the amount of movement expected. This has a two-fold advantage of maintaining a constant bearing area and preventing the lower surface from being exposed to dirt, grit or other contaminants throughout the range of motion.<ref>[https://slidebearings.net/media/fluorogold.pdf Fluorogold Product Literature], Slide Bearings, LP (retrieved 20 January 2014)</ref> Slides plates are arranged in a 'sandwich' formation, which is made of an upper slide plate and a lower slide plate component.<ref>[https://www.pipingtech.com/technical/articles/slide-plate-applications.html Slide Plate Applications] Piping Technology & Products, (retrieved January 2012)</ref> Commonly used in <ref>{{cite web\| url = https://www.pretread.com\| title = for neoprene bridge bearings, manufacturer, elastomeric bridge bearing, pads, high damping rubber bearing, ptfe Teflon products, PTFE sliding, laminated bearings, bridge bearings laminated,bearing pads,ptfe pipe supports, laminated, installation bearings, pot bearings, structural bearings}} </ref> * Oil/gas/chemical industries * Complex steel structures * Post-tensioned concrete structures == See also == * [[Plain bearing]] == References == <references/> [[Category:Bearings (mechanical)]] [[Category:Bridge components]] ▲{{civil-engineering-stub}}
