Curtis Universal Joint Company, Inc. Standard Bore Alloy Steel Joint CJ643BKW1SS

In alloy steel, we have all standard sizes available in stock, ranging from 3/8 inch to 4 inch O.D. with standard bores (one-half of the O.D.), keyways and installed set screws. The 3/8 inch and 1/2 inch joints come with set screws only, while other standard O.D. sizes include keyways. Joints 7/8 inch or larger have Curtis' user friendly Take Apart feature to allow for more specialized modification. Our large inventory allows O.E.M.'s and users delivery on demand. Universal Applications Tractor Steering Commercial Ovens Bowling Alley Cleaning Missile Containers Snow Blowers Curtis Alloy Steel Joints feature 41L40-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 86L20 alloy steel. Center-blocks and pins 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 may not be limited to bores, keyways, set screw holes, square holes and hex holes.
