Customers choose our Take-Apart design for easy installation. But in some cases, Curtis universal joints don’t have to be disassembled at all. We supply a complete line of standard bored joints outfitted with standard bores, keyways and set screws already installed. Talk about ease of matching connecting shafts! We call these u-joints Turn-Key Joints because they are truly complete and ready to go. The 38” and ½” joints come with set screws only, while other standard O.D. sizes include both keyways and set screws. Joints 78” and larger have Curtis’ simple Take-Apart feature to allow for more specialized modifications.

Curtis Alloy Steel Joints feature 4140-grade steel for all forks. Forks of 78 inch diameter and larger have induction-hardened bearing areas for strength and durability. The body (hubs) of the joints remain in an annealed state, which affords free machinability. Center blocks and pins are machined from 8620 alloy steel and are carburized and case hardened to generate superior wear characteristics yet remain ductile, thereby enabling the joint to handle shock loads without experiencing premature failure. Universal joint hub modifications are available per customer specifications, which include but not limited to bores, keyways, set screw holes, cross pin holes, squares, hexes and splines. For assistance in ordering your universal joints, please refer to Curtis’ How to Order instructions or contact the Curtis sales department for more information.
