Talk:Bush (mechanical)

Bush v. bushing
I've always heard it called a "bushing". I notice that bushing redirects to this page. Does anyone call one of these a "bush"? —Ben FrantzDale 13:12, 22 February 2007 (UTC)
 * Yes I do, and so does most of the English speaking automotive industry. It's not a big deal, they are interchangeable. Greglocock 02:42, 25 February 2007 (UTC)

Merge Plain bearing into Bush (mechanical)
Regarding "bushings" as a synonym and the term "plain" bearings:

I attended a seminar by a Product Specialist from the Rexnord Corp, a leading supplier of composite bearings.

His first slide read, "Bearings support a load while permitting motion and maintaining shaft centerline. Bushings plug gaps and holes"

His second slide read, "Cylindrical bearings that support a load without rolling elements are called Plane (not "Plain") Bearings.

-

I think that the person from Rexnord was confusing "his" or a "local" deffinition with the general one. The only link to either plane or plain bearings I could find on Rexnord's web site is in www.rexnord.com/portal/repository/falk/020301.pdf

If you search on their site, you will find that their common term is "sleeve bearing".

If you ask people involved with bearings, plane will have a much lower useage than plain. Plain as in unembelished.

Look up bushing in any dictionary and you are likely to find several uses for it. One of those is going to include the idea of reducing friction.

As part of my job, I try to get engineers to name parts consistantly (an almost impossible task). For part names (these are local definitions) bearings with rolling elements are called BEARING and those without rolling elements are called BUSHING. Things that plug gaps or holes are PLUGS. In the documents where we define the names, we also refer to the ones that define similar names.

Use of descriptive names if always a problem. It varies with regions and groups.

The page should also list synonyms that are commonly used. Sleeve Bearing Bushing Journal Bearing Babbit Bearing (specialized version) Plain Bearing Plane Bearing

DISAGREE WITH MERGE
A bush, or bushing, can be a rubber bush that allows no sliding at any interface. A plain bearing is designed to slip at one or other interface.

Plain Bearing Nomenclature
The term "Bearing" can be properly applied to either a plain bearing or a rolling-element bearing (ball or roller bearing). To those who work with plain bearings, normally the term "bearing" is used to refer to a "half-shell bearing" or a split bearing such as used on crankshafts for big-end connecting rod bearings or main bearings. The term "bushing" is usually used to refer to a full-round bearing such as used for camshafts, automatic transmission shafts, and small end of connecting rods. In the U.K. the term "bush" is normally used; in North America, "bushing" is more common.

While a bushing is indeed a plain bearing, the term "plain bearing" should be an entry under "bearing," and not a separate entry, as the term "bushing" is much more commonly used than "plain bearing. Furthermore, the term "bushing" includes both plain bearings and other non-bearing devices (such as the rubber truck stabilizer on a skateboard), so it doesn't make sense to include bushing under plain bearing.  Thus, incorporate any material in "plain bearing" into "bushing," delete "plain bearing," and include an section under "bearing " entitled "plain bearing," with "more commonly known as a "bushing" included to differentiate.
