Bridge shaft (also known as bridge bearing or support bearing) is an important component in the automotive transmission system, mainly used to support and stabilize the transmission shaft or half shaft, reduce vibration and impact, and protect other transmission components.

Buffer impact force: Bridge bearings can absorb the impact caused by uneven road surfaces, reducing damage to the transmission system.

Supporting the transmission shaft: As the middle support point of the transmission shaft, it prevents excessive deformation of the long transmission shaft due to its own weight and torque.

Attenuation vibration: Reduce torsional and bending vibrations of the half shaft or transmission shaft, and improve driving smoothness.
