Sealing ring classification:

V-shaped sealing ring

It is an axially acting elastic rubber seal ring used as a pressureless seal for the rotating shaft. The sealing lip has better mobility and adaptability, can compensate for large tolerances and angle deviations, can prevent internal grease or oil from leaking out, and can also prevent external splashing water or dust from intruding.

U-ring

Commonly used in the manufacture of reciprocating seals in hydraulic systems. It is widely used in the sealing of hydraulic cylinders in construction machinery.

O-ring

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

It is generally installed in a groove with a rectangular cross-section on the outer circle or inner circle to play a sealing role.

Y-ring

Widely used in reciprocating motion sealing devices.

In addition, there is also a spring tension (spring energy storage) sealing ring, which is a spring added to the PTFE sealing material, including O-shaped springs, V-shaped springs, and U-shaped springs.
