Barden Corporation is a ball bearing manufacturer based in Danbury, Connecticut, USA with factories in Danbury, Winsted, Connecticut and in Plymouth, England. It previously had factories in Bridgeport, Connecticut (Lacey Manufacturing-divested in 2008)〔PEP Press Release, November 3, 2008, http://www.pep-corp.com/news.html〕 and Haverhill, Massachusetts (Pope Spindle-divested in 2003).〔(Pope spindle is acquired by Setco. | North America > United States from AllBusiness.com )〕 Barden specializes in the design, manufacture, repair and overhaul of aerospace and super precision ball bearings〔Fuchs & Steidel, Technology & Engineering, 1973, p399〕 for safety-critical and harsh environment applications〔NASA CP, Volume 3115, p160〕 in a broad range of market sectors, from space〔Goetzel, Rittenhouse, Singletary, Lockheed Missilses and Space Company, Space Vehicles, 1965, p269〕 to aerospace to subsea〔(Bearing inspection is no longer a pain in the neck: News from Nikon )〕〔http://www.bardenbearings.com/scan%20pdf/catalog9.pdf〕 to high performance machine tools〔Agapion & Stephenson, Metal Cutting Theory and Practice, 2006, p138〕 to medical and high performance automotive applications.〔(【引用サイトリンク】title=Super Precision & Aerospace Ball Bearings )〕 == History == Barden was founded by Theodore Barth and Carl Norden (hence the name "Bar-den")〔(The Barden Corporation: Private Company Information - BusinessWeek )〕〔New York Times, Finance & Business, May 24, 1946, p32〕 in 1942 to make precision ball bearings for the Norden bombsight.〔http://library.wcsu.edu/web/about/units/archives/findingaids/warner.xml〕〔(【引用サイトリンク】url=http://www.bardenbearings.com/about.htm )〕 The Norden bombsight required 61 precision miniature and instrument type bearings. Prior to the US entry into World War II, bombsight production levels were planned to be 800 per month; however after the Japanese attack on Pearl Harbor, production was ramped up and reached roughly 2000 units per month by the close of 1943.〔(Carl Norden Biography )〕 The precision level of the bearings required for the bombsight to operate was not available〔(The Secret Weapon )〕 in the domestic bearing industry, driving the creation of Barden.〔Morton, Hudson T.; Bearings (Machinery), 1965, p461〕 Even during the Cold War, Barden bearings would continue to be used on key weapon systems and platforms.〔http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA174324&Location=U2&doc=GetTRDoc.pdf〕〔http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA471183&Location=U2&doc=GetTRDoc.pdf〕 During various growth spurts, Barden Corporation acquired companies that supported the Barden bearing manufacturing business. These included companies like EMO (later renamed Barden UK-allowed entry into the European Market), Winsted Precision Ball Company (bearing rolling elements), Pope Spindle (precision bearings supported machine tools), Lacey Manufacturing(rolling element retainer/cages and other bearing components), and American Powdered Metals of North Haven, Connecticut.〔Hartford Courant, March 30, 1965 p25〕 After severe flooding in the Danbury area in the 1950s,〔New York Times, August 20, 1955 p1〕 Barden Corporation was re-located from downtown Danbury on East Franklin Street〔Aero Digest, Volumes 72-73, 1956 p54〕 in what had previously been a hat factory to its current location overlooking the Danbury Airport.〔New York Times, Finance & Business, September 24, 1957, p50〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Barden Corporation」の詳細全文を読む スポンサード リンク
