Characteristics of Sealed Spherical Roller Bearings

Sealed self-aligning roller bearing is a commonly used rolling bearing, mainly composed of inner and outer rings, rollers, retainers, and seals. Its characteristics can be summarized from the following aspects:

1、 Structural characteristics

Sealing performance: Sealed self-aligning roller bearings are equipped with end caps on both sides of the inner and outer rings for sealing the interior of the bearing. This design can effectively protect the internal structure of the bearing from external damage, such as dust, moisture, etc., thereby extending the service life of the bearing.

Self centering performance: Due to the alignment between the center of the outer ring spherical raceway and the center of the bearing, sealed self-aligning roller bearings have self centering performance, which can automatically adjust the tilt or deflection of the shaft caused by the angle error between the shaft and the bearing seat. This characteristic enables the bearing to be more stable under load, reducing wear caused by angular deviation.

2、 Performance characteristics

Large load capacity: Sealed self-aligning roller bearings can withstand large radial loads and bidirectional axial loads, especially suitable for situations with heavy loads and impact vibration loads.

Low rotational friction: The contact area between the rollers inside the bearing and the raceway is large, and the rollers are spherical in shape, which makes the frictional resistance of the bearing relatively small during rotation, thereby reducing energy consumption and temperature rise.

Long service life: High quality materials and scientific manufacturing processes ensure a relatively long service life for sealed self-aligning roller bearings, reducing the frequency of maintenance and replacement.

Easy installation and maintenance: Sealed self-aligning roller bearings have adjustable stability, making installation and adjustment convenient. At the same time, its sealing performance also reduces maintenance needs caused by external pollution.

3、 Application Fields

Sealed self-aligning roller bearings are widely used in various machines and equipment due to their excellent performance characteristics, such as:

Construction machinery, such as excavators, loaders, bulldozers, cranes, etc., require significant loads and vibrations. Sealed self-aligning roller bearings can provide stable support.

Metallurgical equipment, such as rolling mills, tensile machines, and cooling coiling machines, work in harsh environments and require bearings with sufficient strength and stability.

Mining equipment, such as excavators, loaders, transport vehicles, etc., also need to withstand large loads and vibrations, and work in complex and changing environments.

Power equipment, such as generators, wind turbines, etc., need to withstand high-speed rotation and high temperature environments. Sealed self-aligning roller bearings can provide reliable support.

In summary, sealed self-aligning roller bearings have the characteristics of compact structure, good sealing performance, large load capacity, low rotational friction, long service life, and easy installation and maintenance. These characteristics make them widely applicable in various machines and equipment.
