Flexible Coupling – Slit Type- Clamp Type – Short Type Zero backlash. The flexure allowed by the beam portion of the coupling is capable of accommodating angular and axial misalignment. No accommodating to parallel misalignment. High wrench torque rigidity and sensitivity. Rotation character of clockwise or anti-clockwise is exactly the same. Free maintenance, oil-resist and anti-corrosiveness. FACM-S can’t allow axial deviation caused by offset Offset of angular, parallel, or axial deviation are individual allowed value, so couple reasons of axial offset appearing at same time would reduce the unit allowable value.
