For the castor misspelling, see the discussion here. Omnipedian (talk) 11:08, 23 December 2008 (UTC)

I've read the discussion, and I'd have to disagree with castor being labelled as a misspelling. From what I've read, it seems that castor is an excepted variant. I'm not proposing that the article be changed or anything, but, it would probably be best not to label it as a "misspelling". My source is; it's an online version of the Oxford English Dictionary.

What does 'it' refer to in the following sentence from this article? "Increasing trailing distance can increase stability at higher speeds for wheelchair racing, but may create it at lower speeds for everyday use." —Preceding unsigned comment added by () 15:41, 11 September 2010 (UTC)

It seems to refer to 'flutter' so I changed it->flutter for this. RJFJR (talk) 14:49, 26 October 2012 (UTC)

Rigid Caster[]

How exactly does a rigid caster differ from a normal wheel? If it is fixed, doesn't that defeat the purpose of a caster wheel and make it just an ordinary wheel? (talk) 16:56, 20 May 2011 (UTC)

Good question. I don't claim to know the answer, but here are some things to consider. A wheel is always an ordinary wheel whether it is part of a caster or not. The purpose of a caster is to enable its load to be moved; the only way to defeat that purpose is to lock the caster so it can't roll, yet some casters have locking mechanisms that do just that. AFAIK, casters always have fork-mounted wheels, so it would seem that a forkless wheel assembly (e.g., automobile wheel) is definitely not a caster, whereas a fork-mounted wheel could be a caster, though it's not required (e.g., bicycle wheels). Also, casters are typically self-contained assemblies that can be attached, after the fact, to mechanical loads. Perhaps that explains why bicycle wheels are not considered to be casters.

I object to the rigid caster being called a caster. The whole purpose of a caster is to cast, i.e. to swivel. A non swiveling caster is a wheel, perhaps a "fixed wheel". The term "swivel caster" is redundant. (talk) 18:05, 20 May 2020 (UTC)

Your opinion has some merit. Nevertheless, manufacturers call them "rigid casters" and "swivel casters" to differentiate them -- a fact which cannot be changed by wishing it so. Lambtron talk 18:16, 20 May 2020 (UTC)

The term "caster angle" aka "castor angle" is often confused with what is properly refered to in the article as "trail" or "trailing" and is probably where the "caster wheel" got it's name. This "trail" and the derived ability of the wheel to follow the direction of the load through the swivel (which, ironically, in a caster wheel usually has 0 degrees caster) is what differentiates a "caster" wheel from an ordinary wheel - not the fact that there is a fork attaching it to the load.

Powered Casters[]

I was recently looking up information on powered caster wheels and I haven't seen a independent term for them; "Powered Caster" seems to be the common term. Should the description of casters as 'an undriven, single, double, or compound wheel' be changed or is there a different term that should have be used? If there is a term that should be used a link to that article would be a good addition to this article. () 21:46, 18 January 2013 (UTC)

Good question. It depends on whether "powered" is an attribute of the fundamental caster. Is a powered caster internally driven or or is it driven by an external force acting on the surface of the wheel? Lambtron (talk) 22:46, 18 January 2013 (UTC)


Does anybody know about the history of the word caster? I believe that it comes from the usage of the word cast meaning turn. (see [2])

Proposed Major Change to Article[]

The Institute of Caster and Wheel Manufacturers (ICWM) has created an expanded version of this article (see and would like to propose it as the new base article for the topic, from which others can expand it. The ICWM was formed in 1933 and represents Industry's leading suppliers of casters and wheels (see website located at The ICWM has tried to make it concise and comprehensive and have included citations in the article. Please let us know your comments regarding the change. Michael G. Kay 16:10, 13 June 2016 (UTC) — Preceding unsigned comment added by Mgkay (talkcontribs)


When were caster wheels first invented? Or if we don't know first, how old are they? — Preceding unsigned comment added by () 03:04, 18 November 2016 (UTC)

ICWM performance standards[]

Apparently there's an ongoing slow edit war in which one editor keeps trying to replace a functional reference (provided by Caster Concepts) with an alternative one, based on the claim that a legal action is forthcoming which will accuse Caster Concepts of copyright infringement. This claim may be true but, until such legal action is filed, it makes no sense to prohibit a source based on a third-party's allegation of infringement. Furthermore, as Just plain Bill and I have pointed out, the alternative reference is problematic because the link leads to a paywall. The editor has said that an effort will be made to upload some version of the source content to Commons, which would be an excellent way to solve this problem. In the meantime, I've restored the Caster Concepts reference and recommend that we revisit this issue when a legal action has been filed or a viable alternative source becomes available, whichever comes first.

Unlawful use of copyrighted material owned by the Institute of Casters and Wheels. A cease and desist order is underway against Caster Concepts. Any further attempts to add back this content will result in potential action against Wikipedia for unlawfully distributing copyright material owned by ICWM. (talk) 21:11, 22 March 2018 (UTC)
Per your reference above (i.e. directly from Wikipedia) - "Despite the need to attribute content to reliable sources, you must not plagiarize them or violate their copyrights. Rewriting source material in your own words, while substantially retaining the meaning of the references, is not considered to be original research." — Preceding unsigned comment added by (talkcontribs) 21:19, 22 March 2018 (UTC)
I am in no hurry to see this resolved today, but sooner would be better than later. In the meantime, I would prefer not to see language, on talk pages or in edit summaries, hinting at legal action to be taken against Wikipedia. It is not clear what relationship exists between user:Darcor-rsimmons and ICWM, nor what the status of any putative cease and desist order may be. Just plain Bill (talk) 21:47, 22 March 2018 (UTC)
