Heavy duty keyed shaft coupler single unit for motor repairs
✔️ 1-3/8in bore plus 5/16in keyway on 4-1/2in cold rolled steel body

This single packaged connector acts as a direct mechanical link between rotating drive components like electric motors, reduction gears, and timing pulleys. Shop operators typically install it on factory assembly lines, material handling conveyors, and farming machinery to move power smoothly without slipping under heavy operational loads.

✅ 1-3/8inch central bore diameter for solid shaft fitment
✅ 5/16inch keyway slot to lock against rotational slippage
✅ 2-5/16inch outer diameter running across the steel shell
✅ 4-1/2inch overall body length with dual hex set screws

💡 what sizing factors guarantee secure torque transfer in a keyed shaft coupling setup?
You can easily bolt this solid connector in place for daily industrial work.
- Match the bore size to your drive shaft gauge to stop unwanted wobble
- Pick a keyway width that meets standard profile specs for hard shifting loads
- Check the shell thickness to maintain clear clearance inside tight machine frames
