Wheel-related products (chassis)
Refined Technologies and Products for Roads Worldwide
These are used in the wheel section connecting the wheels and the tires, and they support the heavy vehicle weight and rotate the tires smoothly while receiving external force. JTEKT's products decrease the vehicle weight while promoting the integration of a portion of the surrouding components, and the built-in sensors contribute to improved reliability and functionality.
PRODUCT LINEUP
Wheel bearings have evolved significantly by integrating with surrounding components, based on the needs of cars such as high speed, lower fuel consumption, and maintenance-free operation.
Furthermore, in response to the growing need for safety, various functions have been added.
