Talk:Roller screw

Links to Catalogs
Wizard191 (talk) and I disagree about the appropriateness of links to catalogs in the roller screw article. I included links to Rollvis and Spiracon catalogs, as well as to a CMC web page, which Wizard191 has since removed, citing WP:ELNO. I agree that those references include promotional material, a definite drawback, but argue that the value of other information the references provide overcomes that disadvantage, and, as far as I am aware, there is no specific prohibition of catalogs in the Wikipedia guidelines. The catalogs I linked to have images, details and specific information including sizes, configurations, loading (e.g. dynamic and static), lubrication, mounting, efficiency, applications, lifetime, mechanical equations (e.g. speed, buckling and deflection), etc. The links I provided happen to be some of the most informative and readily available resources on the subject at hand. I believe they are likely useful to anyone seeking more information than the article provides. Thus, I believe they have merit and should be re-included in the article. I welcome other comments on the subject. Catsquisher (talk) 21:20, 22 March 2011 (UTC)
 * In the absence of further objection I will restore the deleted links. Catsquisher (talk) 16:18, 26 March 2011 (UTC)

What are they used for?
By the end of the article I still I have no idea what they are used for. Modal Jig (talk) 17:52, 26 June 2012 (UTC)
 * The topic is pretty esoteric for those not very familiar with mechanical equipment, but the gist is that a roller screw is a machine that can be used very effectively for push/pull applications of many types, especially under high speeds and loads, and with a high degree of repeatable precision. —Catsquisher (talk) 18:32, 26 June 2012 (UTC)
