Coupling Model for Large Ball Screw Applications
April 1, 2022
Handling speeds up to 18,000 RPM, these SFF Miki Pulley Couplings are suited for ball screw applications in machining centers. They provide high torque and torsional stiffness, strength and adequate misalignment, saving unnecessary system bearing wear.
Miki Pulley's latest model SFF Coupling is designed for large ball screw applications on high performance machining centers.
"The SFF Coupling offers exceptional torsional stiffness and strength," said a company spokesperson. "These couplings have rugged designed steel hubs with black oxide finish. This proven Miki Pulley coupling design assures accurate machining center shaft rotation with precise control. The coupling's flexible element gap dampens conductive heat transfer from motor to output shaft. Also important, the coupling provides limited shaft misalignment to alleviate premature system bearing wear. The coupling's aerodynamic profile decreases noise while optimizing performance at high speeds."
SFF couplings are available in single and double element configurations. Bores can be arranged with clamp, taper-lock or keyed styles for specific application requirements.
Basic SFF coupling specifications are:
- Maximum RPM: 18,000
- Maximum allowable torque: 221.27 ft-lbs. (800 Nm)
- Bore size range: 0.709" to 3.15" (918 mm to 80 mm)
- Backlash: Zero
- Ambient operating temperature: -40 °C to 120 °C (-40 °F to 248 °F).
