It is an axial-action elastic rubber Sealing Ring, used for non-pressure sealing of the rotating shaft. The sealing lip has good mobility and adaptability, which can compensate for large tolerances and angle deviations, prevent the leakage of internal grease or oil, and also prevent the intrusion of external splashing water or dust.
2. U-ring
It is commonly used in the manufacturing of reciprocating seals in hydraulic systems. It is widely used in the seals of hydraulic cylinders in construction machinery.
3. O-shaped Sealing Ring
It is mainly used for static seals and reciprocating motion seals. When used for rotational motion seals, it is only applicable to low-speed rotary sealing devices.
4. Rectangular Sealing Ring
It is generally installed in the rectangular-shaped grooves on the outer or inner circle to perform the sealing function.
5. Y-shaped Sealing Ring
It is widely used in reciprocating motion sealing devices.
Additionally, there is spring tension (spring energy storage) called Sealing Ring. This is achieved by adding a spring to the PTFE sealing material. There are types such as O-shaped springs, V-shaped springs, and U-shaped springs.
