Locking Shaft Collar For CNC Machines Heavy Duty With Bore 1.4375 Inch Outer Diameter 2.25 Inch And 0.5625 Inch Thick H7 Tolerance For Minimal Axial Displacement Black Oxide Finish Reduces Wear Ideal For Precise Power Transmission In Large Equipment

Heavy-Duty Locking Shaft Collar for CNC Machines (Single)
✔️ 1-7/16" ID x 2-1/4" OD x 9/16" thick, H7 bore, black oxide

This locking shaft collar is a single-piece, heavy-duty clamp used to locate and stop shafts in CNC machines, linear motion systems, and large equipment. The set-screw design and H7 bore ensure secure positioning and precise alignment in heavy-duty power transmission assemblies.

✅ 1045 carbon steel with black oxide finish for wear resistance
✅ H7 bore tolerances minimize axial displacement on shafts
✅ Set-screw locking style for quick installation and maintenance
✅ Ideal for CNC machinery, conveyors, and heavy-duty power transmission

💡 What is a locking shaft collar and why is a precise bore important?

In plain terms, a locking shaft collar keeps components from sliding along a shaft, ensuring accurate alignment in machines like CNCs and conveyors.

- shaft location and axial stop for precise power transmission - reduces wear and movement under heavy loads - easy on-site adjustments with a standard set-screw - compatible with standard shafts in heavy-duty assemblies
