The axle is one of the most important parts of a railway locomotive or rolling stock. It needs to bear the weight of the train as well as the stresses of rotating and bending while the train is in motion. This can lead to fatigue cracks forming in the axle, which can jeopardize the safety of the train. In order to prevent this from happening, it is essential that the axle is made from high-quality materials that can withstand the stresses of train travel. The axle also needs to be properly lubricated in order to reduce friction and wear. By taking these measures, we can ensure that the axle will last for many years and help to keep our trains running safely. We are able to manufacture the axle for railway coaches, locomotives and urban railcars conform to TB/T 2945, AAR M-101, EN 13261, IRS R-16, JIS E4502, and GOST 22780. The product has been widely used in railway, metallurgy, mining, chemical industry, machinery manufacturing, and other industries. It has become one of the indispensable products in railway transportation.
