Are you asking about the lip shape of the rubber sealing ring. Lip shaped rubber sealing ring is a common sealing component commonly used for sealing piston rods, cylinder barrels, end caps, etc. in hydraulic, pneumatic and other systems. It has good elasticity and self sealing performance, and can effectively prevent leakage.

Lip shaped rubber sealing rings can be divided into two types according to their structure: inner wrapped skeleton type and exposed skeleton type. The internal skeleton sealing ring has better overall elasticity and medium resistance, and is often used in harsh working environments such as high temperature and high pressure. The exposed skeleton sealing ring is more suitable for use in hydraulic cylinders with faster speeds.

In addition, the materials of lip shaped rubber sealing rings mainly include nitrile rubber, hydrogenated nitrile rubber, polyurethane rubber, etc., and their medium resistance properties also vary. For example, nitrile rubber has good oil resistance, but poor wear resistance, high temperature resistance, and cold resistance; Hydrogenated nitrile rubber has good comprehensive properties and can work at higher temperatures; Polyurethane rubber has good wear resistance, high temperature resistance, and cold resistance.

When selecting and using lip shaped rubber seals, the following factors need to be considered:

Scope of application: Select appropriate lip shaped rubber sealing rings based on specific usage scenarios, such as hydraulic cylinder piston rods, reciprocating motion, etc.

Temperature resistance: Select appropriate materials and temperature resistance range according to the actual working environment to ensure the normal operation of the sealing ring.

Pressure resistance: Select a suitable sealing ring for pressure resistance to avoid problems such as leakage caused by pressure fluctuations.

Wear resistance: Lip shaped rubber sealing rings will rub against metal surfaces such as cylinder barrels and end caps during use, so it is necessary to choose materials and structures with good wear resistance to extend their service life.

Installation and maintenance: When installing the lip shaped rubber sealing ring, it is necessary to pay attention to the correct installation method and size to ensure the sealing effect and service life. At the same time, it is necessary to regularly inspect and replace the sealing ring to avoid sealing failure caused by aging, wear, and other issues.

The above is some basic information about lip shaped rubber seals, hoping to be helpful to you. If you have any other questions or needs, please feel free to contact me.
