Heavy Steel Shaft Coupler For Steady Industrial Power Transfer
✔️ 1-1/8 bore 2 inch outside 4 half length cold steel compact frame

Cold rolled steel keyed shaft couplers join rotating parts in machines and drive trains, locking torque between aligned shafts while taking up small alignment gaps. These handy mechanical pieces bolt straight onto motors, pumps, and conveyor frames where operators need dependable power transfer day after day.

✅ One quarter inch keyway slides into the shaft slot and stops rotation drift
✅ Two set screws bite down equally tight to kill any shaft movement
✅ Two inch outside diameter eats through heavy loads without bending
✅ Four and a half inch stretch gives plenty of surface for steady tracking

💡 Why pick a keyed coupling setup when dealing with shaky drive lines?
- Flat key surfaces lock dead against the shaft groove for zero wiggle room
- Simple bolt down installation lets mechanics swap them out in minutes
- Sturdy cold rolled body takes pounding from vibration and sudden shocks
- Standard sizing means you can grab replacements off the shelf anytime
