Bearing sealing ring: the key to protecting the stable operation of bearings

The bearing sealing ring is a device used to prevent lubricant leakage inside the bearing and the entry of external pollutants. According to the different contact methods, bearing seals can be divided into two types: contact and non-contact. Let's learn about different types of bearing seals together.

Contact bearing sealing ring:

Contact sealing ring refers to a sealing structure in which the sealing ring has direct contact with the contact surface on the shaft or bearing. It is usually made of rubber or elastic material, and produces a frictional sealing effect through the contact surface with the shaft or bearing. Contact sealing rings have good sealing performance, but direct contact can cause certain frictional losses and heat generation, making them suitable for medium and low-speed operating conditions.

Application:

Contact bearing seals are widely used in various bearing systems, such as automotive engines, industrial machinery equipment, electric motors, etc. Their main function is to prevent lubricant leakage and external pollutants from entering the bearing system, ensuring the normal operation of the bearings and extending their service life.

characteristic:

Good sealing effect: The frictional contact between the contact seal ring and the shaft or housing can form a good sealing effect, effectively preventing lubricant leakage and external pollutant invasion.

Easy to use: The contact seal ring is easy to install, usually just place the seal ring on the shaft or housing, without the need for additional complex installation steps.

Strong adaptability: Contact seals are suitable for shafts and shells of various sizes and shapes, with strong adaptability and versatility.

Low maintenance cost: Contact seals have a long service life and low maintenance costs, generally requiring only regular inspections and replacements.

Non contact bearing sealing ring:

Non contact sealing ring refers to a sealing structure where the sealing ring does not have direct contact with the contact surface on the shaft or bearing. It usually uses gaps formed by media such as air, liquid, or gas to achieve sealing effect. Non contact sealing rings have low friction loss and heat generation, making them suitable for high-speed operating conditions.

Application: Non contact bearing seals are widely used in various rotating mechanical equipment, such as motors, fans, pumps, etc. It can be used to seal various liquid and gas media, suitable for bearing systems in high-speed rotation and high-temperature environments.

characteristic:

(1) Reduce friction and wear: The non-contact bearing seal ring does not directly contact the bearing, reducing friction and wear of the bearing and extending its service life.

(2) Preventing external impurities from entering: The sealing ring forms a closed space, effectively preventing external impurities such as dust, moisture, oil dust, etc. from entering the bearing system and protecting the normal operation of the bearing.

(3) Preventing lubricant leakage: Non contact bearing sealing rings can effectively prevent lubricant leakage, maintain the lubrication state of the bearing, and improve the working efficiency of the bearing.

(4) Reduce energy consumption: Due to the reduction of friction and wear, non-contact bearing seals can lower energy consumption and improve the energy efficiency of the bearing system.
