1.V-seal is an axially acting elastic rubber seal used as a pressureless seal for rotating shaft. The sealing lip has good activity and adaptability, can compensate for large tolerances and angular deviations, can prevent internal grease or oil from leaking outward, and can also prevent the invasion of external splashing water or dust.

2. O-ring is mainly used for static sealing and reciprocating motion sealing. When used for rotary motion sealing, it is limited to low-speed rotary sealing device. v-type seal is generally installed in the outer circle or inner circle with a rectangular cross-sectional groove to play a sealing role.

3. Y-type seals are widely used in reciprocating motion sealing devices. In addition, there are spring tension (spring accumulation) seal, which is a spring in the PTFE sealing material, there are O-type spring, V-type spring, U-type spring.

4.YX type seal for hole

Product use: Used for sealing the piston in reciprocating hydraulic cylinder. Scope of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders, CPU: hydraulic cylinders for construction machinery and high temperature, high pressure cylinders. Material: polyurethane TPU, CPU, rubber

Product hardness: HS85±2°A Working temperature: TPU: -40~+80℃ CPU: -40~+120℃ Working pressure: ≤32Mpa Working medium: hydraulic oil, emulsion.

5.YX type hole retaining ring

Product use: This standard applies to the cylinder working pressure greater than 16MPa with YX type seal ring, or the cylinder eccentric force, to protect the role of the seal ring. Working temperature:-40~+100℃

Working medium: hydraulic oil, emulsion, water product hardness: HS92±5 material: PTFE

6. YX type seal for shaft

Product use: for reciprocating hydraulic cylinders in the piston rod seal range of application: TPU: general hydraulic cylinders, general equipment hydraulic cylinders. CPU: hydraulic cylinders for construction machinery and high temperature, high pressure cylinders.

Material: polyurethane TPU, CPU, rubber product hardness: HS85 ± 2 ° A working temperature: TPU: -40 ~ +80 ℃ CPU: -40 ~ +120 ℃ working pressure: ≤ 32Mpa

Working medium: hydraulic oil, emulsion

7. YX type retaining ring for shaft

Product use: This standard applies to the cylinder working pressure greater than 16MPa with YX type seal ring, or the cylinder eccentric force, to protect the role of the seal ring. Working temperature:-40~+100℃
