SUMMARY

The discussion centers on sourcing universal joints with specific features, particularly counterbores at the ends for flat plate mounting. The user is primarily interested in joints suitable for use as bearings in a Stewart platform or hexapod motion platform, rather than for torque transmission. The desired size is approximately 1/4 inch or 6mm in diameter. Participants suggest that while size is flexible, the power handling capacity is typically a critical factor, and creating an adapter may be a viable solution.

PREREQUISITES
  • Understanding of universal joint design and applications
  • Familiarity with Stewart platform mechanics
  • Knowledge of bearing types and their functionalities
  • Basic skills in CAD software for custom adaptations
NEXT STEPS
  • Research manufacturers of universal joints with counterbore features
  • Explore CAD design techniques for creating custom adapters
  • Investigate bearing specifications for Stewart platforms
  • Learn about torque transmission requirements in motion platforms
USEFUL FOR

Engineers, designers, and hobbyists involved in robotics, motion control systems, or custom mechanical assemblies who require specific joint configurations for their projects.

Does anyone know a manufacturer or supplier of joints like the one shown here:

The main feature I'm looking for is the counterbores at the ends that allow mounting to a flat plate. Almost all the ones I've found are made for connecting shafts.

Thanks

So the size and power handling capacity doesn't matter? I would suggest that's usually more important and that getting an adaptor made would be the easy part.
 
Right, the size can be anywhere around 1/4in or 6mm in diameter. I'm mainly using these as bearings and not to transmit torque, as part of a Stewart platform/hexapod motion platform.
