High speed Miki Pulley SFD Couplings are rigid, metal disc couplings featuring zero backlash and high torsional stiffness with high concentricity for precise shaft alignment in demanding machine tool spindle applications.
Handling system speeds up to 20,000 RPM, they maintain concentricity within .001 TIR. The SFD couplings feature self-centering, single bolt clamping at both coupling ends. This patented bolt and set screw clamping mechanism provides accurate and fast installation.
SFD couplings have a compact, low profile design for applications where space is limited. They are ideal for machine tool applications. RoHS compliant, they are available in three models in bore sizes ranging from 6.00 mm to 22 mm. Transmittable torque for these sizes range from 2.2 Nm to 25 Nm.
In addition to the SFD high speed coupling line, Miki Pulley designs and manufacturers a complete line of motion control components. These include flexible shaft couplings, shaft hub locking devices, clutches, brakes and speed control devices.
