No Bull Standard Jaw Coupling Hub Built Sick Out Of Sintered Iron With Nine Millimeter Bore And One Point Seven Five Inch Outside Diameter Featuring Three Millimeter Keyway For Serious Shop Rig Work

Robust Iron Jaw Coupling Hub For Smooth Power Transmission
✔️ 9mm bore plus 1.75in OD fitted with 3mm keyway for motor drives

You pick up this single replacement unit to reconnect spinning shafts on industrial pumps, blowers, and conveyor frames. You slide it onto your drive spindle where tiny parallel gaps or sharp angular tilts usually wreck drive chains. The 9mm (0.35in) inner hole catches your shaft shoulder neatly while the 1.75in (44mm) outside width leaves plenty of clearance in tight housing boxes. That 3mm (0.12in) side groove locks your set screws straight so torque never jumps across the connection.

✅ Sintered iron manufacturing builds a solid core that takes heavy impact shocks
✅ Flexible center zones absorb torque spikes before they crash into your bearings
✅ Direct retrofit shape drops into compatible assemblies without drilling mods
✅ Corrosion blocking finish keeps your shop floor gears running clean longer
