You already know the important role our couplings play in heavy-duty equipment, from cranes and hoists to pumps and compressors. But coupling can also make or break applications requiring advanced, precision motion control—like surgical robots, medical device manufacturing, medical imaging, lab automation, semiconductor equipment and industrial robots.

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. Take our line of elastomer jaw couplings, 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 aluminum 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.

Metal Bellows. Our metal bellows couplings 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
  • Nominal torques: 0.1 to 5,000 Nm
