Application Guidelines

Selecting the Right HAM

For best results, we recommend selecting HAMs based on your load requirements with a 1.5-2x safety factor. For example, if your application requires a 50N force, the HAM-75 would be appropriate.

When working with antagonistic pairs, select HAMs with matched force ratings to ensure balanced operation. For joints requiring higher precision, using HAMs on the upper end of their force rating is not recommended.

Common Applications

  • HAM-75: Robotic hands, educational models, lightweight linkages, facial expressions for animatronics
  • HAM-150: Standard limb actuation, articulated joints, general purpose robotics, mid-sized grippers
  • HAM-300: Load-bearing joints, industrial manipulators, heavy-duty applications, replacement for pneumatic cylinders
