High-temperature resistant skeleton oil seals are generally divided into single-piece and assembled types. The assembled type allows for cross-interchangeability between the frame and lip material, and is typically used for unique seals.
From the perspective of sealing effectiveness, characteristics, structural features, operating conditions, and sealing principles, oil seals can be classified into various forms and designated with different names. However, by convention, the rotating shaft lip-type sealing ring is generally referred to as a sealing ring, while the packing seal and dynamic sealing (typically involving repeated motion) are collectively referred to as sealing components.
