OIL SEAL KUBOTA AQ8270P Agricultral Oil Seal

Product details:

Agricultural machinery seals, also known as oil seals, are important components of agricultural machinery and are widely used. The performance and quality of agricultural machinery directly affect its reliability in use.

Loose oil seal is the main factor causing oil leakage. When the bearing wears and forms grooves, even if a new oil seal is replaced, it still cannot be sealed. This is because the contact pressure between the oil seal lip and the shaft decreases, resulting in a small interference between the oil seal lip diameter and the shaft diameter after installation, which cannot form a sealing effect;

The main reasons for poor sealing are:

1. Poor quality of oil seal manufacturing;

2. Poor quality of shaft or bearing;

3. Improper use and maintenance;

4. Improper installation;

5. Improper storage and adverse effects caused by environmental pollution;

Agricultural machinery seals are mainly used for sealing engine crankshafts and camshafts

Sealing of transmission systems for agricultural machinery such as tractors, reducers, mixing locomotives, and coal mills

Sealing of transmission systems for agricultural machinery and construction machinery such as tractors and excavators

Oil seals are widely used in agricultural machinery engineering and equipment processing industries

The main characteristics of agricultural machinery oil seals

The outer part of the oil seal is cylindrical to ensure static sealing of the cavity - using a rubber outer edge with an inner metal skeleton: using an exposed metal skeleton outer edge, most require polishing and coating with anti-corrosion coating.

The sealing lip equipped with springs ensures the sealing reliability of the dynamic and static seals of the shaft. After long-term development and research, the sealing lip structure of the oil seal has been improved to good performance, thereby improving the sealing reliability over a wider load range

Material selection of agricultural machinery oil seals

Agricultural machinery oil seals usually made of fluororubber material have better corrosion resistance and high temperature resistance than those made of IE material. It is recommended to use agricultural machinery oil seals made of PTPE sealing material under conditions of no lubrication, pure dryness, and multiple media. The sealing lip has sufficient lubrication ability, greatly reducing lip wear.

A single agricultural machinery oil seal is not suitable for sealing two different media. The presence of large amounts of chemicals increases the impact on the material performance of the oil seal. The compatibility of the oil seal with the sealing medium should be determined through laboratory testing. The adaptability of different rubbers to the sealing medium used in oil seals. The contamination of the sealing medium may be due to the negative impact of sealing medium contamination on the sealing characteristics of the cavity casting. It is necessary to pay attention to keeping the cavity clean as much as possible.

Naibeike has developed a variety of COMBI seals designed for construction equipment, specifically engineered to overcome harsh and highly polluted working environments while providing essential lubrication functions. The combination of multiple seals in one provides additional barriers and sealing edges for equipment. The design of COMBI seals varies depending on the equipment's properties and operating conditions.
