SFS Model Coupling



This basic SFS variant offers more axial flexibility than its counterparts. When paired with a floating shaft spacer, the SFS may transmit torque at a greater DBSE (distance between shaft ends), while absorbing misalignment. Using high grade steel with a black oxide finish, the SFS coupling offers exceptional torsional stiffness and strength. The flexible element gap also dampens conductive heat transfer from the motor to output shaft.

Single and double element configurations are available as-well as varying lengths of an intermediate floating shaft. Bores can be configured with clamp, taper-lock, or keyed styles.
