Robust 1-1 1/4 Inch Solid Shaft Coupler Keyway
✔️ C1018 Steel, Black Oxide, 1-1/4 Bore, 2-1/8 OD, Keyway

This heavy duty alignment coupling connects two rotating shafts while locking torque transmission securely in place. Mechanics and machine builders rely on this part for industrial motors, conveyors, pumps, and workshop equipment that demand steady power delivery without slippage.

✅ One piece C1018 mild steel housing provides strong resistance against torsional stress
✅ Precision 1/4 inch by 1/8 inch keyed bore eliminates play during high RPM operation
✅ Dual hex socket set screws grip the shaft firmly for fast installation and adjustment
✅ Black oxide surface coating protects against shop rust and handles frequent grease contact

💡 Why are solid shaft couplers considered so handy for workshop machinery?
Finding the right mechanical joint depends on matching your drive components properly.

- Standard keyed bores accept both square and tapered drive ends without modification
- Hex set screws align perfectly with machined flats to resist rotational shock
- Heavy gauge carbon steel bodies handle sudden load shifts better than aluminum alternatives
