Exceptional corrosion resistance for Extreme Environments

Harsh environments call for corrosion-resistant materials. Some environments, for example in marine or underwater applications, require machines and components with an exceptionally high resistance to corrosive elements.

Due to the extremely harsh underwater environment, all components must have exceptional resistance to corrosion. Belden uses higher-grade stainless steel for universal joints in these situations. The yokes of the universal joints are made of extremely corrosion-resistant 316L stainless steel. To prevent galling and to improve the joints’ friction properties, the yokes’ contact surfaces are PTFE-coated. The pins and blocks are also manufactured from 316L stainless steel and are protected with grease-packed boots.

To provide higher strength and improved wear resistance, Belden’s standard stainless steel joints have AISI 303 stainless steel yokes and AISI 416 steel pins and blocks. Standard single joints can be modified with a variety of stainless steel grades, including 304, 316, 17-4 and 15-5, to meet specific applications’ requirements. Diameters range from 1/2 " (13 mm) to 6" (153 mm) with a standard operating angle of 35 degrees. From underwater oil field equipment to drinking water conveying systems and food processing applications, Belden’s universal joints and complete shaft assemblies are available in a variety of stainless steel grades and with various hub configurations, lubricants and additional protective measures such as boots, for use in a wide range of applications in even the most corrosive environments.
