68-5643-56 Cushion Coupling (Set Screw Type) QJ70UR-20-28
Features
- Zero backlash.
- Vibration & sound absorption.
- Cushion is pipe shaped, highly flexible and long life.
- Cushion material with high torsional rigidity
- Small selectable.
- Hub material is aluminum die cast, and moment of inertia is small.
- [Cushion Coupling]
- Cushioned couplings absorb eccentricity, declination and rotational vibration by deforming a cylindrical cushion surrounded by hub projections.
- The six cushions are completely independent, allowing each to deform effectively to easily cope with misalignment and rotational vibration.
- There are 4 types of cushion materials, and the difference in hardness shows the difference in torsional and eccentric characteristics.
