Seal structure is a variety of forms, according to different modes of movement can be divided into static seal and dynamic seal, dynamic seal is divided into reciprocating movement and rotating movement. The more common seals are O-ring, rectangular ring, V-ring, U-ring, Y-ring, Yx ring and so on. Seal structure, material, hardness is different, its application is also different.

①O-Rings

It is mainly used for static sealing and reciprocating sealing. When used for rotary motion seals, limited to low speed rotary seals.
When used for dynamic sealing, star ring can be selected, and its dynamic sealing performance is better than O-ring, but its price is higher than O-ring.
O-ring is used to withstand high pressure, can be used with a stop ring.

②Square Rings

It is generally installed in the groove of the outer circle or the inner circle with a rectangular cross section。

③V-Rings

It is an axially acting elastic rubber sealing ring, used as a non-pressure sealing of the rotating shaft. The seal lip has good mobility and adaptability, can compensate for large tolerances and Angle deviations, can prevent internal grease or oil leakage, can also prevent the intrusion of external splashing or dust.

④U-Rings

Seals used for reciprocating motion in hydraulic systems. It is widely used for sealing hydraulic cylinders in construction machinery. The general material is polyurethane, supporting dust ring, guide sleeve, etc., to form a set of hydraulic seal components.

⑤Y-Rings

It is widely used in reciprocating motion sealing devices. The representative seal is a pan-plug seal, which has spring tension inside the pan-plug seal, also known as the spring energy storage seal ring. The flooding seal is to add a spring to the PTFE sealing material, including O spring, V spring, U spring and so on.

⑥YX type sealing ring
YX type seal ring is divided into hole and shaft, the seal is suitable for hydraulic cylinder seal, the material is polyurethane and rubber.
