The oil seal in the hydraulic system is a key component to ensure system sealing, mainly used to prevent hydraulic oil leakage and air entry, thereby ensuring the normal operation and safety of the system. Hydraulic oil seals are usually made of materials that are resistant to high pressure and high temperature, which can withstand harsh hydraulic environments.
The main types of hydraulic oil seals include:

V sealing ring: commonly used in hydraulic cylinders.

R35 R37 Type seal with Canvas

Bonded Seal: commonly used for static sealing of end faces of various joints.

O-ring: commonly used for static sealing and low-speed rotation/reciprocating motion.
