Aircraft
Today I received a call from [department regarding] mishap investigation.  He told me that maintenance found the LH nose gear's inner bearing failed and damaged the axle.  He said the Flight data shows normal landing for the last ten cycles.  We flew the aircraft on this flight; from ZZZ to ZZZ1.  From the time we took control of the aircraft; pre-flight through parking at ZZZ1 we had no visual or mechanical indication that there was any problem with the nose gear. Taxiing; takeoff and landing were all performed normally and no known stress put onto any of the landing gear during our control of the aircraft.
The left nose wheel axle was discovered bent and the bearing had failed after the aircraft was parked at the gate. No abnormal appearances or indications were noted during any portion of the walk around or any phase of flight including landing and taxi in. The flight was uneventful and both the takeoff and landings were normal during the flight.
Flight Crew reported being informed that maintenance had discovered a wheel bearing on the left hand nose wheel assembly had failed and damaged the axle. Flight crew reported no difficulties or unusual sounds during normal operation.
