Stainless-Steel Double Universal Joints

Belden’s stainless double universal joints provide the same reliability and service life as the single universal joints, with a maximum combined working angle of 90°. Double universal joints provide accurate positioning and flexibility under higher operating angles. The joint yokes are 303 and the pins & blocks are hardened 416 stainless steel to provide higher strength and improved wear resistance. Components can be made from other grades of stainless steel. For additional environmental protection, pins & blocks can be covered by lubricant retaining boots.
