Belden’s complete line of universal joints and shaft assemblies include a full range of military certified universal joints used in auto racing/gear change linkage, military personnel carriers and aerospace applications. Universal joints are designed and manufactured for a variety of applications including high lift actuation and control mechanisms for aircraft where low deflection rates, high strength to weight ratios and long service life are essential. The heavy-duty MS 271 military standard universal joints have undergone qualification and acceptance testing by a testing lab and the U.S. Department of Defense. The MS joints meet or exceed the requirements of military specification MIL-J-6193. To qualify the universal joints, a variety of extensive and rigorous testing was completed. Reaction frames were designed and fabricated to perform torsional play, tightness, static torque, endurance and lubrication retention tests. The Belden MS series of universal joints is the design that is mandated for all government/military and aerospace applications and is also utilized in performance and NASCAR racing. The military standard joint’s high strength pin and block design can be modified into various materials such as aircraft 17-5 and 15-5 and marine grade 316 and 316L stainless steel.
