Talk:Bushing (isolator)/archive

Local usages of terms belong in a dictionary, not an encyclopedia. Wiktionary may be interested, but I suspect Urban Dictionary is probably the best place for it. -- Finlay McWalter | Talk 17:32, 8 December 2005 (UTC)[reply]

You're probably right there. I hadn't heard of these sites before. Thanks (original article was not mine by the way) :) -- Diom1982

If Wiktionary take it (I've honestly no ideas what their criteria for inclusion are; they may well require evidence of it's being used by a nontrivial sized population) then wikipedia can host a special "wikitionary has a page about xxx" tag, so that anyone who comes here looking for it will find the wiktionary page. The same isn't true for Urban Dictionary, as a) it's run by an entirely different organisation, and b) it clearly lets in any old crap ;) -- Finlay McWalter | Talk 18:34, 9 December 2005 (UTC)[reply]

Merge with bush (mechanical)

I propose bush (mechanical) be merged with this article. Any comments? —BenFrantzDale 20:54, 9 January 2006 (UTC)[reply]

A merge looks sensible, essentially they are the same. The only thing is with terminology, perhaps it's a regional or American English vs. English English thing, but the object is a bush, not a bushing. Graham 00:24, 10 January 2006 (UTC)[reply]

One possibility is to do the Bush (mechanical)-Bushing merger, and at the same time split off the electrical meaning into Bushing (electrical). The two concepts are very different in nature. We could then possibly do with a disambiguation page. --BillC 21:11, 12 January 2006 (UTC)[reply]

That sounds like the right approach. —BenFrantzDale 21:33, 12 January 2006 (UTC)[reply]

Done! BillC 22:15, 12 January 2006 (UTC)[reply]

definite need for disambiguation

I aggree that the mechanical object is a bush (although I don't doubt that some people mught call it a bushing)

I dunno about the electrical thingy

But the further meaning for a bushing is in the manufacture of glass fibre, its a big plate of metal, usually platinum / rhodium with lots of holes, the glass dribbles out of the holes, and forms fibres as it falls.

The wikipedia glass fibre page links to bushing, but that then tells you about the mechanical rubbery type of object, which really is entirely different.

Agree - disambiguate - move the current page to Plain bearing first:

Bushing (plain bearing)
Bushing (threaded pipe adapter)
Bushing (electrical thingy)

One problem - a plain bearing may be a bush, but a bush (even in this limited sense) is not a plain bearing. What about bushes made from rubber or polyurethane? They are not considered plain bearings in the usual sense, since a plain bearing allows one part to rotate inside another with a sliding friction between, whereas many bushes only allow very limited rotation or compression of the pliant material. That's why, when I want to buy something like that, I ask for a "bush" and not a "plain bearing". This merge seems likely to me to cause a worsening of the precision of the different terms.

Bushings can be either plain bearings or bushes. Merge "bush" into "bushings." Merge "plain bearings" into "bushings," too. Mugaliens 16:20, 10 August 2006 (UTC)[reply]

Old discussion from plain bearing

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

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.
