Hub
/hʌb/noun
The central part of a wheel, fan, or rotating mechanism; by extension, a central place of activity.
Did you know?“Hub” began as a dialect word for the projecting center of a wheel, and its rise to mean a center of power is a perfect example of how physical mechanics become social metaphor.
