The Type RU Roller Ring from THK features double-row roller structure and integrated inner and outer rings said to result in 20 to 30% higher rigidity than competitor models. The Type RU's use of small rollers is also said to reduce differential slip and therefore the torque required for rotation is small. Installing the unit is simplified due to the inclusion of mounting holes on the inner and outer rings.

Belden Inc.'s line of universal joints and shaft assemblies include a range of military certified universal joints used in auto racing/gear change linkage, military personnel carriers and aerospace applications. The 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.
