New SFF Flexible Couplings from Miki Pulley

Plymouth, Minnesota: Offering exceptional torsional stiffness and strength, SFF couplings from Miki Pulley are designed to ensure accurate shaft rotation with precise control. SFF couplings are manufactured with rugged steel hubs and a black oxide finish for maximum corrosion protection. The coupling’s balanced aerodynamic profile decreases noise, while optimizing performance at high speeds. Additionally, the coupling’s flexible element gap dampens conductive heat transfer from motor to output shaft, while providing limited shaft misalignment to alleviate premature system bearing wear.
Miki Pulley’s SFF couplings are available in single and double element configurations and with bores that can be arranged with clamp, taper-lock, or keyed styles for your custom application requirements.   sff.jpg - Miki Pulley
