Curtis supplies and stocks a complete line of standard bored joints in all 14 sizes. Standard bores are 1⁄2 of the O.D. The Curtis Take-Apart advantage allows the hubs on 7⁄8″ diameter and larger joints to be economically machined or reworked per customer specifications.
Curtis Alloy Steel Joints feature 4140-grade steel for all forks. Forks of 7⁄8 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.
