The Spaniard promised to donate £50 for every minute he played with La Roja at the U21 European Championships in Poland last month.
Bellerin accumulated 381 minutes of play for Spain, starting all but one match in the tournament.
The 22-year old donated the money to the British Red Cross, who are helping victims of the tragedy.
Eighty people are currently presumed dead after the tower burned down in west London last month.
