Exceptional Corrosion Resistance for Extreme Environments

The harsh environments of marine or underwater applications require machinery and components with exceptionally high resistance to corrosive elements.

Belden uses specialty stainless steel for universal joints for such operating conditions. The yokes of the universal joints are made of extreme-corrosion resistant 316L stainless steel. To prevent galling and 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 application requirements. Diameters range from 1/2" (13 mm) to 6" (153 mm) with standard operating angles of 45°. 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 various hub configurations. Protective measures such as boots and lubricants can also be added.
