Metro Cast Steel Axle Box for Railway Vehicle

Our Metro Cast Steel Axle Box is a precision-engineered railway component designed for metro, passenger coach, and freight wagon bogie applications. The axle box serves as the critical interface between the wheelset and the bogie frame, housing the rolling bearings that allow the axle to rotate while transmitting vertical and lateral loads from the vehicle body to the wheelset. Manufactured through advanced casting processes, our axle boxes meet rigorous international railway standards for safety, durability, and performance in demanding urban transit environments.

Product Overview

The axle box (also referred to as axlebox or journal housing) is a fundamental component of railway bogie systems. It functions as the suspension connection point between the axle bearings and the bogie frame, working in conjunction with axle box springs to permit vertical movement and sliders to prevent lateral movement. Our cast steel axle boxes are designed for reliable operation on metro networks worldwide, supporting axle loads up to 25 tons with proven performance.
