MOTORCYCLE

Each motorcycle is usually equipped with 20 to 30 bearings. These bearings are used for important rotating parts such as engines, transmissions, and wheels to support driving, and are responsible for reducing friction and driving the engine power to the wheels. Therefore, the performance required for motorcycle bearings is to achieve smooth rotation through low friction, low vibration and high durability. These performance affect the fuel consumption and safety that are closely related to our life. ZYS always pays attention to these details and strives to develop bearing and optimize the bearing design to improve the quality of life and protect the global environment.
