@nam.nhat859: Fishing reel line roller not spinning? Dirt, salt buildup, dried grease, or a seized bearing can cause the roller to stop turning. If ignored, it can increase friction, twist the line, and cause premature line wear. Clean, inspect, and lubricate the roller to restore smooth movement. #FishingReelRepair #LineRoller #LineRollerRepair #FishingReelMaintenance #ReelCleaning
