Product overview
The side bearer wear plate of railway freight car is usually used on the two springs of the railway freight car bogie, which is the contact surface between the carriage and the bogie. The nature of the side bearer wear plate of the truck requires that it must have a large enough friction coefficient, so as not to increase the lateral force of the contact surface, resulting in the reduction of the lateral acceleration of the bogie, so as to ensure that no meandering motion occurs during the running of the vehicle, to ensure driving safety, Our truck side bearer wear plate and its production process improve the impact performance and service life and shorten the reaction cycle.
