要旨 With regard to automotive wheel hub units, customers traditionally have sought improvements such as longer service life, higher rigidity and reductions in size and weight. But in recent years, their demands for such sealrelated performance as muddy-water resistance and lowered torque have been increasing. The seal is an important hub unit component that functions to prevent water or foreign matters from entering into the bearing. This report introduces a seal-periphery rubber molding process for preventing muddy-water intrusion, a low-temperature seal for securing suffi cient muddy-water resistance in cold regions, and a super low-torque seal with muddy-water resistance.
キーワード hub unit, seal, muddy water, low torque, low temperature
