When a single universal joint is not enough to compensate for all misalignment, a combination of joints can be a good solution.
The Belden double universal joint provides the same reliability and service life as the single universal joint with a maximum combined working angle of 90°. Double universal joints provide accurate positioning and flexibility under higher operating angles.
Double Joints take lower loads than single joints; this is a recommendation by the joint standard due to the additional bending moments and forces that are applied to the center section and which are transferred to the joints as additional loads.
Belden's double universal joints are available in a wide variety of materials and finishes. Lubricant retaining boots are recommended for operation in corrosive environments.
Double universal joints can be manufactured either as a double joint, with a double yoke in the center section, or as a 'double butted joint', with two single joints 'butted' together.
