What's the difference between an oil seal and a seal? Is it the same thing?
The seal is a general term for all products that are sealed. They include O rings, oil seals, seals for piston hydraulic cylinders, dust rings, and so on,
Broadly speaking, seals include oil seals. In a narrow sense, it can be understood that seals can be used to seal oil or to seal air, i.e., oil seals and pneumatic seals. But in the sealing field, oil seal is used for rotating the skeleton oil seal, and non professional fields, such as some used seal factory engineers, said the oil seal is used to seal oil seal, including static seal and reciprocating rotary oil seal oil seal and seal oil seal.
The oil seal, also known as the rotary shaft lip seal, is a seal used in the rotation of the shaft. It is different from the seals used for reciprocating movement of the piston!
