Integration guide

Choosing hubs and couplings for wheel, motor and shaft integration

Universal hubs and couplings help connect MECAWHEEL mecanum or omni wheels to motors, shafts and drive assemblies when the standard interface does not match the platform.

The important details are bore size, keyway, fixing method, bolt pattern, shaft support and available mounting space. A suitable hub can often avoid full wheel customization.

Key selection points

  • Confirm shaft diameter, keyway and fixing method.
  • Match bolt pattern and wheel interface.
  • Check available width, alignment and maintenance access.

Common uses

  • Motor-to-wheel connection
  • Custom AGV and robot drive modules
  • Replacement or adaptation of existing shafts

When do I need a universal hub?

Use a hub when the wheel and motor or shaft interface do not match directly, or when a removable mechanical adapter is preferred.

What dimensions are needed for hub selection?

Share shaft diameter, keyway, fixing method, bolt pattern, available width and the wheel model you plan to use.

Can a hub reduce custom wheel cost?

Often yes. A suitable hub or coupling can solve integration requirements without changing the wheel body.
