Questions about this item

Will the sleeve bearing need lubrication or replacement after long-term operation?

The sleeve bearing is sealed and not user-serviceable; once it wears out the entire 4028 fan must be replaced.

At 0.84 A draw, what thermal limit appears first during continuous running?

The motor reaches its rated high-temperature threshold before any other component, so sustained loads are capped by that thermal limit.
