Description
The 1" X 1-1/4" Steel (Black Oxide) Step-Up Shaft Adapter Coupling with Keyways is a precision-machined component designed to increase an existing shaft to a larger output size without replacing the entire shaft. Crafted from black oxide steel, it provides durability, wear resistance, and corrosion protection. Its clamp-type design provides secure, non-marring attachment without welding, while the integrated keyways help prevent slipping and improve torque transfer between the shaft and connected components. Ideal for machinery, motor and drive systems, automation equipment, conveyors, and shaft repair or modification.
