Kingrail railway bogie outer springs are key elastic components used in the primary or secondary suspension system of railway rolling stock. They are designed to support vehicle load, absorb dynamic impact, reduce vibration transmission, and maintain stable running performance under long-term railway operation.
The outer spring is commonly installed together with an inner spring to form a combined suspension spring group. This structure helps improve load distribution, enhance fatigue resistance, and ensure reliable suspension performance for locomotives, freight wagons, passenger coaches, metro cars, and other rail vehicles.
Kingrail manufactures railway outer springs according to customer drawings, samples, and technical specifications. Materials can be selected according to project requirements, including 60Si2CrVA, SUP9A, SUP10, 50CrV4, or equivalent spring steel grades. Through controlled forming, heat treatment, shot peening, surface protection, and dimensional inspection, the spring can achieve stable mechanical performance and long service life.
