    In addition to its sealing function, hub rubber seals also play a crucial role in reducing friction and wear in the machineryhubhub rubber seal. By providing a smooth surface for the rotating parts to glide on, the seals help to minimize friction, heat, and wear, thus extending the lifespan of the equipment.
    The design of PU oil seals also plays a significant role in their functionalitypu oil seal. They often feature a-like structure that creates a tight seal against the mating surface, preventing the leakage of oil or other fluids. This design, combined with the elastic memory of polyurethane, allows the seal to recover its original shape after compression, maintaining a consistent seal even under fluctuating pressures.

    3. Heat Resistance During operation, wheel bearings can generate significant heat. Quality grease seals are designed to withstand these high temperatures, ensuring that they do not deform or fail, which can lead to grease leakage or contamination.
