Part No. 3126-30CF Weld Yokes, 1310 Series, Butt Dia 3.000", Tube Dia Wall 3.260X0.130

The "CF" suffix on 3126-30CF indicates this weld yoke is machined for use with carbon-fiber driveshaft tube rather than aluminum or steel. Carbon-fiber tube is never welded -- the yoke is bonded into the tube end using a two-part structural adhesive (typically a methacrylate or epoxy system approved for the specific fiber/matrix combination) or secured with a mechanical press-fit and roll-pin. The butt diameter of 3.000" provides the bonding surface area. The 3.260" x 0.130" tube wall is a common specification in performance CF driveshaft builds offering a significant weight saving -- a 36" CF shaft at this diameter weighs roughly 40% less than the equivalent 4130 steel tube. Verify adhesive cure temperature, bond gap, and any surface preparation (anodize removal, abrasion) per the adhesive manufacturer's data sheet before assembly.
