SFR
The Servoflex SFR high damping performance shaft coupling, is designed for high speed and high precision use in combination with Servo- and Steppermotors. Zero backlash with strong torque transmission. By using an HNBR element, vibration is quickly damped compared to flexible couplings with metal elements.
- Hubs out of high-strength aluminum alloy
- High damping characteristics
- Max. 10‘000 rpm
- Zero Backlash
- 5 to 25 Nm
