birkosit dichtungskitt seals are typical representatives of oil seals. The term 'oil seal' generally refers to skeleton oil seals. The function of an oil seal is to isolate lubricated components in 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. Based on structural form, they can be divided into single-lip skeleton oil seals and double-lip skeleton oil seals. The secondary lip of a double-lip skeleton oil seal serves as a dust shield, preventing external dust and impurities from entering the machine interior.
