Description
A U-joint can sometimes be eliminated by using a 2″ straight extension, called a coupler. The coupler can be welded and/or pinned to the un-splined end of a shaft. We offer shafts that are splined only on one end in 3 lengths. 5 inch, 16 inch, and 36 inch. The 1″-48 and 1″ DD couplers have a 1-1/4″ hole that will accept either an adapter to reduce inside diameter to 3/4″ smooth or another splined or 3/4″ DD coupler. The coupler assembly would have to be pinned and/or welded together. Welding the coupler is acceptable because there are no moving parts to damage. Couplers are available in the same spline or Double D sizes as u-joints. Couplers and adapters are available in steel only.
