What Is an American Type External Axle？
American type external axles are trailer axles with brake drums and wheel hub assemblies positioned outside the main axle beam. This design allows for easier access during maintenance, inspection, and replacement of brake components compared to internal brake axles. These axles are widely used in heavy-duty semi-trailers due to their durability and ease of service.
