dtb seals are a typical representative of oil seals; the term "oil seal" generally refers to skeleton oil seals. The function of an oil seal is generally to isolate components requiring lubrication within transmission parts from the external environment, preventing lubricating oil leakage. The skeleton acts like rebar in concrete components, providing reinforcement and enabling the oil seal to maintain its shape and tension. Structurally, they can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals.

Based on skeleton type, they can be classified as internally embedded skeleton oil seals and externally exposed skeleton
