Explore Our Couplings for Advanced Motion Control Systems

Share This Article:

As we already mentioned in previous blog posts RINGFEDER® Couplings not only play an important role in heavy-duty equipment like cranes and hoists or pumps and compressors. But also our couplings can make or break applications requiring advanced, precision motion control—like surgical robots, medical device manufacturing, medical imaging, lab automation, semiconductor equipment, and industrial robots.

Motion control can be defined as a sub-field of automation or an engineering technology that deals with moving individual parts of a machine in a controlled manner. Motion control is a bit of a specialty in automated control systems, and its use is not basic, as it can provide advanced machine functionality.

The industry is getting day by day more capable, and more productive with time on account of the growing use of high-grade automatic equipment, machine tools, high-level medical equipment, sensors, and many others. The rising concerns for industrial safety have also paved the way for the real growth of this industry.

A Rundown of Our Couplings

When it comes to precision-driven motion control systems, the right coupling can bring a lot to the table. These components compensate for misalignment, limit torque in high-inertia machines and can provide critical vibration dampening—all of which reduce component wear while keeping downtime to a minimum.

Elastomer Jaw Couplings RINGFEDER® GWE

Take our line of Elastomer Jaw Couplings GWE, for example. Used in high-accuracy applications like medical positioning systems, these couplings dampen vibration and compensate for radial, axial and angular misalignment. Thanks to a preloaded elastomeric spider, they also avoid backlash when transmitting torque.

In addition, elastomer jaw couplings offer various connection options and incorporate different Shore hardness levels, correlating to torsional stiffness. They also integrate lightweight aluminium hubs, which keeps their moment of inertia low. Thanks to these features, elastomer jaw couplings are ideal for complex motion control applications, including precision drives, robotics systems and more.

  • Backlash-free, through pre-stressing
  • Axially pluggable
  • Vibration damping
  • Compensation of radial, axial and angular misalignment
  • Electrically isolating
  • Temperature range: -60° to +250°F / -30° to +100°C
  • Nominal torques: 0.3 to 1920 Nm

Metal Bellows Couplings RINGFEDER® GWB

Our Metal Bellows Couplings GWB are another option and are useful whenever you need to transmit torque and rotary movement from shaft to shaft with very high torsional stiffness. In addition to compensating for misalignment due to their stainless-steel design, metal bellows couplings avoid backlash despite changes in rotation speed, direction or torque—a characteristic that significantly improves service life in critical applications.

Other notable features and benefits of metal bellows couplings include:

  • High torsional stiffness
  • Low moment of inertia due to compact size
  • Simple and safe assembly
  • Wear- and maintenance-free, reducing downtime
  • Temperature range: -22° to +212°F / 30° to +100°C
  • Nominal torques: 0.1 to 5,000 Nm
