Product Description
Product Overview
The railway freight car side bearer wear plate is installed on the two springs of the bogie, serving as the critical contact surface between the carriage and bogie. This component requires a sufficiently high friction coefficient to prevent increased lateral forces that could reduce bogie lateral acceleration. Our advanced high polymer composites ensure no meandering motion occurs during vehicle operation, guaranteeing driving safety while improving impact performance, extending service life, and shortening reaction cycles.
