Classification and application of rubber sealing ring?
V-shaped seal ring is a kind of elastic rubber seal ring with axial action, which is used as the non pressure seal of the shaft. The sealing lip has good mobility and adaptability, can compensate large tolerance and angle deviation, can prevent internal grease or oil from leaking out, and can also prevent external splash or dust intrusion.   
O-ring is mainly used for static seal and reciprocating seal. When used for rotary motion seal, it is limited to low-speed rotary seal device.   
Y-shaped sealing ring is widely used in reciprocating sealing device. In addition, there is also a spring tension (spring energy storage) seal ring, which adds a spring into the PTFE sealing material, including O-ring, V-spring and U-spring.
