Heavy Duty Flexible Jaw Coupling Featuring 12Mm X 12Mm Bore With Rock Solid Elastomeric Spider For Cnc Servo And Stepper Motors Built Tough For Smooth Torque Transfer And Zero Flex Drama In High Speed Industrial Setups

1-piece flex coupling for steady servo torque delivery
✔️ 12mm bore shaft, 30mm width, 50mm length, 1045 steel

This single unit links drive axles while damping vibrations during routine operation. You will mount these hubs on printer rods or pump spindles to keep RPMs steady without shaking loose.

✅ Fits shafts measuring twelve millimeters diameter on both sides
✅ Absorbs shock loads and stops direct metal contact inside hubs
✅ Compensates for slight wobble on angled or offset shafts
✅ Holds up to heavy spinning speeds without bending or slipping

💡 Why choose a jaw coupling over solid gear drives for noisy setups?
This handy upgrade solves alignment headaches without replacing expensive motor mounts.
- Tame harsh ringing from servo motor shifts under heavy load
- Allow easy sliding onto ten millimeter and twelve millimeter axles
- Protect ball screw assemblies from sudden impact torque kicks
- Simplify maintenance swaps when upgrading old machine frames
