Rear wheel hub bearing seals and O-rings play an important protective role in the vehicle's rear axle system, mainly used to maintain the relative stability of the internal environment of the bearing cavity.

Through the combined use of seals and O-rings, the impact of external environmental factors on internal components can be reduced during wheel hub and bearing system operation, thereby maintaining the smooth operation of the rear wheels.

When the original rubber seals show signs of aging, deformation, decreased elasticity, or weakened sealing performance, they should be replaced promptly.
