Aliminium Joints

for special Military und Aerospace applications



When it comes to military applications, your product must stand up to the harshest of
environments. Recently, the development and manufacture of a complete shaft
assembly for an amphibious assault vehicle demonstrated Belden’s commitment to
tackle the toughest applications.

Designed to withstand both nuclear and
biological contamination, the joint yokes and
shaft of the vehicle were constructed of 7075-
T651 aluminum to provide a lightweight, highstrength,
corrosion resistant solution. It was
necessary to modify standard pin and block
designs in various materials to create a
custom assembly.

The bushing and pins were made from hardened 416
stainless steel to combat corrosion and prevent galling
and premature wear of the yoke components. The pin
and block section of the universal joints were covered
with neoprene boots to prevent contaminates from
invading the assembly. The boots were molded
specifically for the shaft assembly to protect the joints
and provide maintenance-free operation for extended
periods of time. The end result was a solid solution that
met the customer’s exact application specifications.

Our needle bearing inch line can be manufactures out of aluminium whether using steel needle bearings or AISI 303, 316 or 416 steel bushings to avoid galling. Based on this design we can manufacture single and double joints as well as drive shafts.
