Sealing performance of UK200 series outer spherical bearings

The sealing performance limitations of UK200 series outer spherical bearings mainly include the following aspects:

1. Restrictions on sealing materials: UK200 series outer spherical bearings adopt a double-layer sealing structure, but their sealing materials are usually organic materials such as rubber or polyurethane. These materials may undergo chemical reactions or physical changes in certain media (such as petroleum, solvents, etc.) or high temperature environments, resulting in reduced sealing performance or failure.

2. The accuracy of the sealing surface: The sealing performance of the UK200 series outer spherical bearings has a great relationship with the accuracy of the sealing surface. If the sealing surface is not smooth or has defects (such as scratches, pits, etc.), the sealing performance may be reduced or even leakage may occur.

3. Limitations of the sealing structure: Although the sealing structure of the UK200 series outer spherical bearings can provide better dustproof performance, it still has certain limitations regarding the intrusion of some small particles or moisture and other substances. If these substances enter the inside of the bearing, they may affect the performance and service life of the bearing.

4. Restrictions on usage conditions: The sealing performance of UK200 series outer spherical bearings is also affected by usage conditions. For example, when used in extreme environments such as high temperature, low temperature, and high pressure, sealing performance may be adversely affected. In addition, in some special applications, such as food, pharmaceutical and other industries, the sealing performance requirements of bearings are more stringent and need to meet specific hygienic standards.

There are certain limitations in the sealing performance of UK200 series outer spherical bearings. Various factors need to be considered in specific application scenarios to select the appropriate bearing type and sealing solution. At the same time, attention should be paid to maintenance and upkeep during use, the sealing performance and internal status of the bearing should be checked regularly, and problems should be discovered and solved in a timely manner to ensure its normal operation and service life.

UK200 series outer spherical bearings are a variant of deep groove ball bearings with a tapered inner ring that can be installed directly on a tapered shaft or used in conjunction with a tightening bushing. This type of bearing has a high load-bearing capacity and a small radial cross-section, and is suitable for bearing combined radial and axial loads, mainly radial loads. Its application fields and characteristics are as follows:

1. Agricultural machinery field: UK200 series outer spherical bearings are widely used in the agricultural machinery field because this type of bearing can withstand large radial loads and axial loads, and has automatic alignment, large load capacity, long service life, and sealing It has the characteristics of excellent performance, easy installation, and prevention of outer ring rotation.

2. Industrial machinery field: UK200 series outer spherical bearings are also widely used in the field of industrial machinery, especially in those applications that require large loads, dust-proof sealing and stability. Its features include high load-bearing capacity, small radial cross-section, good sealing performance, and easy installation.

3. Other fields: In addition to applications in agricultural machinery and industrial machinery, UK200 series outer spherical bearings can also be used in other applications that need to bear combined radial and axial loads, such as automobiles, aerospace, etc.

It should also be noted that the UK200 series outer spherical bearings have a relatively low rotational speed, so they may not be suitable for use in some high-speed applications. In addition, its sealing performance is also subject to certain limitations, and various factors need to be considered in specific application scenarios to select the appropriate bearing type and sealing solution.
