Gurley Models SCA, SCD, and SCEShaft Couplings

SCA and SCE have clamp-style shaft attachment and are recommended for most industrial encoders. SCD attaches to each shaft with an M2 set screw and is for smaller instrument-grade encoders with shaft diameters of 4 mm max. The The 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.
