The railway vehicle bolster, generally manufactured by casting. As one of the main load-bearing components of three-piece type bogies, it transmit vertical, longitudinal and lateral vehicle loads, and enable rotational movement between the bogie and the car body.

Each bolster is normally designed with:

➤ 1 center plate, which restricts relative movement between the car body and bogie and transmits loads in different directions.

➤ 2 mounting interfaces for side bearings, different side bearings (such as gap-type or constant-contact elastic side bearings) can be fitted according to vehicle performance requirements.

➤ 4 mounting interfaces for friction dampers, different types of wedges can be installed according to vehicle performance requirements.

➤ Assembly interfaces for brake system components.
