Zero-Max CD couplings with aluminium hubs have low weight and low inertia making them an excellent choice for servomotor and other precision motion control applications.
Zero-Max CD couplings with aluminium hubs have low weight and low inertia making them an excellent choice for servomotor and other precision motion control applications.
Available in single and double disc pack models, these couplings have high torsional stiffness and zero-backlash.
These aluminium hub CD couplings provide the same torque as the steel hub versions along with a 15 to 20% increase in the couplings' rotational speed rating for most models.
Both single and double disc pack models combine the best features found in steel disc and elastomeric couplings through the use of a patented open arm disc design made of rugged composite material.
This unique design provides the high misalignment capacity found in many elastomeric couplings but with higher torsional stiffness.
compared with steel disc couplings, CD couplings with aluminium hubs offer superior damping and isolation of shock and vibrating loads, including elimination of fretting corrosion and dramatic reduction of stress fractures at the bolt hole locations.
The CD coupling also provides excellent chemical and moisture resistance in hostile environments that prove difficult or impossible for elastomeric or steel disc couplings.
The aluminium hub CD Single Flex models are available in either clamp style or keyway with set screw style hubs from 1.85 to 6.00in diameters.
They handle speeds from 5200 to 17,000rev/min and have torsional stiffness of 203 to 4687Nm/deg depending on size.
The aluminium hub CD Double Flex models are available in either clamp style or keyway with set screw style hubs from 1.85 to 6.00in diameters.
They handle speeds from 4400 to 17,000rev/min and have torsional stiffness of 96 to 2282Nm/deg depending on size.
CD couplings are also available with custom designed disc packs for virtually any type or style of application.
