SFF-(N) Model Disc Coupling

The additional plate spring (disc-pack) connection bolts on the SFF-(N) servo disc 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.

• Maximum allowable torque: 221.27 ft-lbs (300Nm)
• Bore size range: 0.315” – 1.654” (8mm ~ 42mm)
• Backlash: Zero

SFS Model Disc 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 disc 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.

• Maximum allowable torque: 590.05 ft-lbs (800Nm)
• Bore size range: 0.315” – 1.654” (8mm ~ 42mm)
• Backlash: Zero

SFM Model Disc Coupling

The SFM disc coupling was developed in response to demanding spindle tool applications. It can perform at high speeds with precise rotation. The outside profile is free of irregularities that would produce noise during high speed rotation. Also, the SFM offers a centering pressure flange in the bore to ensure concentricity. The double elements offer ultra-high rigidity with limited flexibility.

• Maximum allowable torque: 221.27 ft-lbs (800Nm)
• Bore size range: 1.102” – 3.15” (28mm ~ 80mm)
• Backlash: Zero

SFH Model Disc Coupling

With a 5900 ft-lbs (8000 Nm) torque rating, and maximum outer diameter of 10.32” (262mm), the SFH is intended for high power applications in large industrial equipment.

The metal plate spring and steel hub construction allows for misalignment flexibility while offering rotational rigidity and precision.  Also, it is available in a double-element floating shaft configuration.  Floating shafts are offered in specific sizes, or made to customer length requirements.

• Maximum allowable torque: 5900.50 ft-lbs (8000Nm)
• Bore size range: 0.866” – 4.528” (22mm ~ 115mm)
• Backlash: Zero
• RoHS compliant
