The additional plate spring (disc-pack) connection bolts on the SFF-(N) servo coupling provide higher torsional stiffness, while accepting limited misalignment. Using high grade steel clad in a black oxide finish, the SFF-(N) offers exceptional corrosion resistance pair with torsional stiffness and strength. The flexible element gap also dampens conductive heat transfer from motor to output shaft.
Single and double element configurations are available. Bores can be configured with clamp, taper-lock, or keyed styles.
