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.

Innovative Universal Joint Solutions for Mission Critical Applications

Aerospace and Defense Universal JointsBelden Universal's Aerospace and Military Standard universal Joints (also called cardan joints) are widely requested for private, commercial and military aircraft. They are manufactured to perform according to the most rigorous operating criteria. Our components deliver low torsional backlash, high strength-to-weight ratios and long service life.



Belden customizes high-strength pin and block universal joints and drive shaft assemblies using a variety of hub and connection methods, internal and external splines.


Military Standard (MS) Universal Joints

Belden’s military universal joints meet or exceed MIL-DTL-6193 specifications. In special cases when measured against stringent quality controls, Belden’s standard military universal joints can also be deployed in aerospace applications, including steering, wing flap control, fuel actuation and more. 



Belden Universal has achieved AS9100D Certification for manufacturing products in compliance with the highest global quality system for providing safe and reliable products to the Aircraft, Space and Defense (AS&D) industry. In certain aspects, Belden’s capabilities surpass some of the most stringent AS9100 standards. Read Press Release.


Materials and special coatings for high strength-to-weight ratio and extreme corrosive environments include precipitation hardened stainless steel, cadmium or zinc plated alloy steel, 17-4 / 15-5 PH stainless steel, aluminum, aircraft grade alloys and marine grade 316 and 316L stainless steel.


Digitzed Inspection Records

For easier maintenance of data, Belden transitioned to a paperless inspection system. As opposed to traditional paper records where the operator manually checks off inspection and tool requirements, the software automates, simplifies and speeds up procedures and allows all members of the production team to view live data at any time. It specifies what features to measure, the proper tools for measuring and selects inspection specifications for the various features and pieces.


In-House Testing

Aircraft Universal Joint

To ensure the optimal performance of parts through thousands of operation cycles, Belden custom-manufactured a state-of-the-art in-house testing machine which provides immediate feedback on performance. Belden’s setup is exceptionally efficient, with a superior test cell that benefits customers through faster delivery times and lower costs.
