I ordered two Havells fans from online. I received two types with almost the same features except the following one, which is:

  1. Double ball bearing ceiling fan
  2. Single ball bearing calling fan

I am confused now, which one is better? Which is newest? Which one I need to return?

A double bearing fan will have a longer life than a single bearing fan. The double bearing fan will have a bearing supporting the motor and fan shaft in two locations, rather than one.

A single bearing fan may have a bushing, or just a cantilevered shaft. This will cause the fan to be more difficult to balance and more susceptible to wear.
