Vibration/Resonance Damping Coupling
Zero-Max is the leading provider and coupling manufacturer of precision motion co
Zero-Max is the leading provider and coupling manufacturer of precision motion control products worldwide. The ServoClass product line is known for its reliable high-performance operation. The new ServoClass®-HSN series provides another option alongside the field-proven ServoClass Double Flex and ServoClass Single Flex metal disc models for applications that are experiencing higher levels of vibration and noise. The innovative design of the ServoClass-HSN utilizes proven components of the ServoClass Coupling along with the enhanced damping characteristics of the HSN center element.
ServoClass HSN Couplings deliver the precision and control you require and are ideal for high-gain, high speed response stepper motor and servo motor motion control applications that are paired with lower natural frequency driven components.

Servoclass-HSN Coupling Features
- Enhanced Control - ServoClass-HSN Couplings provide stable control in stepper/servo motor applications that are experiencing higher levels of vibration/noise
- Highly Saturated Nitrile (HSN) material integrated into the center element damps vibration/noise better than alternatives
- Optimal torsional stiffness for high performance use in high-gain dynamic applications
- RoHS Compliant - Eco-Friendly, with no banned substances
- Low hysteresis ensures repeatable, precise positioning
- Low inertia for high-speed applications
Additional Servoclass-HSN Coupling Features
- High Damping Performance
- Zero-Backlash
- Good Torsional Stiffness
- High Misalignment Capacity
- Electrical Isolation between hubs
- Fast, Easy Installation

ServoClass-HSN Power Transmission Coupling Applications
The ServoClass-HSN Coupling is ideal for applications with systems that don't require as high of torsional stiffness as a metal-disc coupling, but will benefit from the ultra-quick vibration damping aspects of the unique center element - such as many high speed feed screw and linear actuator applications in the semiconductor industry.We have extensive experience supplying critical industrial motion control products to virtually any industry, including:
- Packaging, printing
- Semiconductor machinery
- CNC machine tools
- Wind turbines, forestry
- Construction equipment
- Servo motor-driven machines and more
