KTR RADEX® -NC – Servo Disk Couplings
The RADEX-NC steel disc servo-motor couplings were designed specifically for the motion control technology which requires zero backlash torque transmition, but high torisional stiffness.
- Zero Backlash shaft coupling with double flexing elements for shaft to shaft connection.
- DKM insert allows the coupling to compensate for more parallel misalignment.
- Axial plug-in design allows for blind assembly.
- Frictional shaft to hub connections for higher Torque.
- Inch bore sizes machined to AGMA 9002-A86 class 1 fit.
- Inch key sizes machined to ANSI b-17.1.
- Metric bore sizes machined to machined to ISO H7 fit.
- Metric key sizes machined to DIN 6885-JS9.
