Flexiable | Spiral beam coupling The flexure allowed by the beam portion of the couping is capable of accommodating angular, parallel, and axial misalignment. Rotation character of clockwise or anti-clockwise are exactly the same. Free maintenance, oil-resist and anti-corrosiveness. 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. Ordering Example:
