Models SCA,SCD and SCE are flexible-diaphragm, zero-backlash shaft couplings that are designed to accurately transmit system motion to an encoder while protecting the encoder's bearings from overloads caused by moderate amounts of installation misalignment. The SCDattaches to each shaft with an M2 set screw and is for smaller instrument-grade encoders with shaft diameters of 4 mm max. The SCA and SCE have clamp-style shaft attachment and are recommended for most industrial encoders.MODELLENGTHX DIA, MM [IN]KINEMATICACCURACYWITHPARALLELOFFSET P MMANDANGULARMISALIGNMENT 0.09TORSIONALRIGIDITY, N-M/RAD [IN-OZ/ARCS]MAXIMUMPARALLELOFFSET, MM [IN]MAXIMUMAXIALEXTENSIONORCOMPRESSION, MM [IN]MAXIMUMANGULARMISALIGNMENTMOMENTOF INERTIAWEIGHT, G [OZ]MAX.
