Oil seal is a common name for general seals, which simply means the seal of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in the transmission system, and also refers to general liquid substances). It isolates the parts that need lubrication from the output parts in the transmission parts to prevent the lubricating oil from leaking. The seals used for static seals and dynamic seals (generally reciprocating motion) are called oil seals.

Seal ring category
V-ring: Axially acting elastic rubber sealing ring, used as a pressure-free seal for rotating shafts, which can compensate for large tolerances and angular deviations.
U-ring: Commonly used for reciprocating seals in hydraulic systems and widely used for sealing hydraulic cylinders in engineering machinery.
O-rings: Mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing devices.
Rectangular sealing ring: Generally installed in a groove with a rectangular cross-section on the outer circle or inner circle to perform a sealing function.
Y-type sealing ring: widely used in reciprocating sealing devices.
Z-Spring tension (spring energy storage) seal: A spring is added to the PTFE sealing material. There are O-type springs, V-type springs, U-type springs, etc. They can adapt to a wide temperature range and seal various liquids, chemicals and gases.
YX type sealing ring for holes: used for sealing the piston in reciprocating hydraulic cylinders, made of polyurethane TPU, CPU, rubber, etc.
YX-type seal ring for shaft: used to seal the piston rod in reciprocating hydraulic cylinders. The material is similar to the YX-type seal ring for holes.

Selection method
Consider pressure factors: V-rings, bellows seals, etc. can be selected for high-pressure environments, and O-rings can be used for low-pressure environments.
Focus on the state of motion: Y-rings, skeleton oil seals, etc. are suitable for dynamic seals, and rectangular rings can be used for static seals.
According to the medium and temperature: NBR nitrile rubber seals can be selected for contact with oil media, FKM fluorine rubber seals are suitable for high-temperature resistant scenes, and bellows seals can be used in corrosive environments.
Combined with the installation space: U-rings are more suitable for small spaces, and combined seals can be considered for complex working conditions.
Based on the accuracy requirements: Star rings are a better choice for high-precision and low-friction occasions.
