Advantages of UK300 series outer spherical bearings

The advantages of UK300 series outer spherical bearings are mainly reflected in the following aspects:

1. Greater load capacity: Compared with the UC200 series, the UK300 series has a greater load capacity. This makes it more suitable for applications that bear greater radial and axial loads.

2. Automatic self-aligning ability: UK300 series outer spherical bearings have self-aligning capabilities and can automatically adjust the shaft center position to a certain extent to adapt to changes in different shaft diameters and eccentricities. This self-aligning capability enables the bearings to better adapt to changes in radial load, thereby improving the equipment's operating accuracy and stability.

3. Double-layer sealing design: UK300 series outer spherical bearings adopt a double-layer sealing structure, which can effectively prevent dust, moisture and other impurities from entering the interior of the bearing. This excellent sealing performance enables the bearing to maintain a better lubrication state during operation, thereby extending its service life.

4. Suitable for extreme environments: Due to its excellent sealing performance, UK300 series outer spherical bearings are particularly suitable for applications in extreme environments, such as high temperature, low temperature, high pressure, etc.

5. Easy installation: UK300 series outer spherical bearings are more convenient to install. They can be installed directly on the tapered shaft or used in conjunction with an adapter sleeve. No special tools or techniques are required.

Overall, UK300 series outer spherical bearings have significant advantages in load capacity, self-aligning, sealing performance and extreme environmental adaptability, making them perform well in various mechanical applications.

The difference between UK300 series outer spherical bearings and UK200 series outer spherical bearings is mainly reflected in the following aspects:

1. Load capacity: The load capacity of UK300 series outer spherical bearings is greater than that of UK200 series, and can withstand greater radial loads and axial loads.

2. Tapered inner bore: The inner bore of UK300 series outer spherical bearings is a tapered inner bore with a ratio of 1:12, while the inner bore of UK200 series outer spherical bearings is a light series tapered inner bore (UC200 series) or a heavy series taper. Inner hole (UC300 series).

3. Cooperation method: UK300 series outer spherical bearings can be used with adapter sleeves, while UK200 series outer spherical bearings are usually installed directly on the tapered shaft.

4. Sealing performance: The sealing performance of UK300 series outer spherical bearings is better than that of UK200 series, which can better prevent dust, moisture and other impurities from entering the interior of the bearing.

5. Usage environment: Due to its excellent sealing performance, UK300 series outer spherical bearings are particularly suitable for applications in extreme environments, such as high temperature, low temperature, high pressure, etc. The UK200 series outer spherical bearings are usually used in general environments.

To sum up, there are differences between UK300 series spherical bearings and UK200 series spherical bearings in terms of load capacity, tapered inner bore, fitting method, sealing performance and use environment. It is necessary to select the appropriate model according to the specific application scenario.
